    Well, I wish this issue was as simple as a software problem. All of my SD DTiVos (7) are Zippered and locked at version 6.2-01-2-321.

    One of my DSR7000s has recently developed this issue. I first thought the HDD had gone south, most pixelation issues I've dealt with involved HDD issues. True to course, if I yank the S-Vid all is well, plug it back in and it reappears almost immediately. I'm hoping that I won't see further degradation as I need to use both composite outputs in my current config. If I do see further problems I'll swap out a power supply with one of the other fully functional DTiVos and report the results back here.

    I've been searching for someone to describe the problem that my HDVR2 is having and this thread comes close, but not exact. Here's what's happening:

    No matter which tuner or which channel, locals or the classic "cable" channels, I get a video problem akin to something like bad tracking on a VCR. My video is jumpy. If I pause at certain points, the video scrolls on the screen like the vertical hold is messed up. Some times it's fine with certain camera angles. Other times the video is garbled. It's fine in the same places with an 8 second replay and garbled in the same also.

    I've tried swapping the SAT IN cables. I have a HR10-250 with no problems at all. Tried swapping cables with that. I've tried using composite instead of SVideo. Tried different inputs on my TV, both SVIDEO and composite. Tested the SV and composite on the tv with different devices, no problem with the TV. Tried the Tivo on a different TV, same problem.

    Is there anything else I can do? Anyone know what the problem is? A push in the right direction would be appreciated if it's been answered already, I just can't find it yet.

    Thanks in advance.

    It definitely isn't a software issue, I had a hard drive with 3.1.1e on it and it still had the same exact problem.

    Also, I didn't see anyone mention this exactly but when I left my svideo cable plugged into the tivo, and unplugged it from my tv, the problem went away. So the signal, not the cable being plugged in, is the issue.

    Other than never using svideo again, or someone mentioned replacing the power supply, has anyone else resolved this issue?

    I just finished replacing my power supply and have the same pixelation problems. It could be that the power supply I purchased has the same defective qualities as my old power supply (possible, I bought it off ebay to save $40). But more likely the problem lies with the motherboard. Very frustrating indeed!

    I deal with CCS a lot and they fix the receivers properly and do a great job. And not real expensive. They do a complete repair for $100 and that incluides both tuners as well as rest.
    If you notice the s-video outputs are near what I will call a "hot spot" and that is why you may get the problems you have. Someone techinal could explain what I call a "hot spot" better and name it.

    I have exactly the same problem.
    Ever since I got 6.3e, tuner 2 breaks up on channels over 200.
    Did the above test and got the same breakup on 201 and transponder 23 signal goes on and off.
    Unplugging S video doesn't change anything.

    I had this problem with a Samsung SIR-S4080R unit and lived with it for aobut a month before I was able to understand what was happening. I sent it to CSS Corporation (800-354-3114) for repair. I had it back in less than a week and it is now working fine. They charged $100 including return shipping. It was a great service experience!

    I've been having the same issues, and blaming 1. 6.3e 2. Dish position slipping(?) 3. HD going bad or some other mysterious issue.

    Well, I've got my HD upgrade running in the basement (HDVR2 upgraded to 120, and now getting a 200Gig). And I see 6.3f is coming (someday.) And, my Dish position isn't that bad (worst is 60%, most at 90%.)

    And then I find this thread.

    And, since I'm upgrading the HD, I have the case off. And, I gotta say, as a victim of the Apple iBook video chip separation (google "ibook fire video repair") and as an amateur vintage arcade enthusiast, I think we have a likely classic case of some solder gone bad folks.

    Those satellite cables are thick and heavy. My WAG guess? Thats enough weight and enough time has flexed the boards, and there's a solder trace somewhere that is shorting. And the S-video is directly next to #2. The s-video in or out is probably just a way to add or lose pressure that fixes the intermittent short. (Hence reports of it only working for a while.)

    This damn board is locked in with twisted metal tabs and torx screws. And even if I pulled it up, it's got teeny tiny traces that my craptastic soldering skills are powerless against.

    And so, cudos and $'s to those folks at CCS who've figured out just what is breaking, how to take the boards out, and how to solder them back properly (if that's what the problem actually is).

    I just have to decide how long I want to live with either a. composite vs. s-video or b. all my kid's shows being f'd up. :confused:

    I had the S video Jack hooked up to a DVD Recorder and it just died, so I cannot get a signal on the S video jack on anything. RCA model Direct Tivo. Just realized the jack is garbage as are the connections to the board for that jack. Broken what do you expect I just use the RCA cable video jack.

    I also had a crew in here replacing my HD Tivo HR10 with the HD HR21 at no charge. I was not able to get my two RCA's swapped for free only an HD to HD free swap. But the repair guy said if one of my RCA units was broken they would upgrade you for free. I suggest giving them a call tell them no picture or pictures breaks up. When the Sat guys arrive reattach the S video cable. FYI they will also change out the ant for free. Besides at some point they have to replace all the old Tivo units anyway. These installers don't give a hoot what they do as long as they are told to do it.

    After one day I find the new system is OK but not as easy as the Tivo software; but I love all the HD stations. The new box also works with a standard TV so you don't have to have all the latest gear but a. One major drawback is you cannot run a separate off air antenna through the box and no coax connectors out but I always used the TVs input anyway, Plus caller Id on screen. Also has Ethernet that will connect to the network but serves no function yet. But it has been only one day so I have much to figure out.

    has standard s video and yellow RCA outputs for older TVs as well as one RGB and one HDMI out so it pretty much is universal for any TV built in the last 10 years.

    Give them a call see if they will do a swap for free worst case is they say no and use continue to use he yellow video jack. I would not mention this works.

    Hey, brand new poster here, but I wanted to share my experience with the S Video / missing transponders experience.

    My situation was identicle to the OP, and thanks to everyone's advice here, I am back up and running by simply switching from S Video to Composite. So, to all that helped troubleshoot this problem, I humbly give thanks!

    Ok - conspiracy theory alert!

    How 'bout this: Both tuners use software to handle the video output through the gizmo (tech talk for the whatchamacallit) that feeds the S-video out as well as the composite out. The S-video is dramatically better than composite, even on an analog TV.

    In order to demonstrate how much better the HD is than SD on S-video, the algorithm for the output signal sent to the S-video jack uses a lower signal to noise ratio now than it did before. The firmware for processing the output might be independent of the software that runs the DVR... Just a theory. ;-)

    Now, what about the OPEC conspiracy to use ...

    I was having terrible pixel problems on TNT and Bravo on my R10 and on Superstation on my Standard definition Hughes.

    I have waited to see if they come back but no, they have all disappeared since 6.3f was circulated.

    I am still having some intermittent problems with reboots and other stuff but the pixel problems are in the past.

    I'm guessing all R10's are going to start needing hard drive soon, so you might want to consider purchasing one (weaknees.com and dvrupgrade.com for example) . I don't know about you, but my wife was constantly filling up our old hard drive with her programs till we got a new one.

    OK, for all of you folks who are having the tuner problem, you'll definitely want to read this. I was, and was just about at the point of sending it in for repair when I decided to disconnect the unit and take it to another part of the house and hook it up to a different satellite cable (knowing full good and well that wasn't the problem). After I moved it, the unit would no longer power up. Great, I thought. Now I can't even watch the shows I've recorded that were OK. So I decided to head over to Ebay and look for a used DSR704. I found one, won the auction, and the guy I bought it from was local, and was nice enough to bring it to me and refund my shipping costs. After I confirmed that the unit was working OK, my curiosity got the better of me. I pulled the power supply out of the newly purchased unit and put it in the old one. Guess what? The old unit now works perfectly! The point is A BAD POWER SUPPLY CAN DEFINITELY CAUSE TUNER PROBLEMS! My used unit cost less that a replacement power supply, and now I'm going to take a stab at repairing the faulty PS. There is a website that illustrates a bulging capacitor on this exact PS and how to repair it. That particular capacitor isn't bulging on mine, but one closeby is. Now if I can just find the part and brush up on my soldering skills, I might have 2 working DSR704's :)

    Hope this feedback helps some one.I have concluded that on my samsung sir tuner 2 started pixalizing when i started using the 2nd composite feed.First composite going to slingbox second composite going to zone 2 video switcher ,svideo going to local room.Using all these outputs caused issues on my tivo.I had to get rid of svideo feed and use compsite and this cured.I would rather use svideo feed but oh well.I was even ok using 1 svideo and 1 composite.As soon as i used 2nd composite problem started.Thanks to all who contributed to this thread....Cole
