    How would you know? You haven't read it.:D:D:D


    Others (I'm looking at you, lawn mower) will do a much more thorough job of ruining my day up close and personal than you could ever manage over the interwebs, even if you were actually trying to, which I'm sure you're not.

    As for inconveniencing me by posting here, it would have inconvenienced me more if you had not, because then I would have been denied the opportunity to kid around with you. :)


    But seriously, don't be to quick to write off the past as being without instructional value.

    So I had the TWC guy out yesterday with no resolution. We looked at everything and he couldn't figure it out. Our setup is as follows:

    Main line comes in the house into a 2-way splitter. One goes to the modem and the other to a 15db amp. That amp feeds a 3-way splitter. The two -7 dB ports feed my TA's.

    How do I check the levels from the TA? I asked him to do that but we forgot. Is it something I can do? I did have him leave me some 6dB inline attenuators in case I need to knock down the signal some and he left me a new coax line that I may run to see if it is a bad cable run to this particular tv. I'm not convinced that is the problem though because all the local channels work. Is that an accurate statement?

    So to reiterate, here is what happens:

    With Tivo powered and TA powered (solid green) I can watch local HD channels no problem. As soon as I try to tune to an SDV channel the attached picture pops up on the screen.

    Is the amp really needed? I have never had good luck with amps and upstream signals, even when they are supposed to be non-filtering.

    The tuning adapter on my browser must be malfunctioning, as I have recently started receiving posts that are a total non-sequitor :)

    Probably not. The house was originally wired with a 6 way splitter so in that case maybe. I could take it out with little effort.

    Try it and see. If removing that doesn't help, you can always put it back.

    The Tuning Adapter has to send a message back up to the cable company somehow to say "Hey, feed this channel we want to watch to us".

    If the way it feeds that message back up the line is through the co-ax on it's own special frequency instead of having to have an internet connection, maybe that signal isn't able to travel "upstream" through that amp that's perhaps only designed to pass stuff going "downstream".

    Has any SDV problem ever been fixed by sending a technician out to someone's house? ;)

    Yes, but only if the technician was from Dish Network or DirecTV.

    Then swap the TAs around and see if the problem follows them.

    If it does, get the one the problem followed replaced.

    I'm a little leery to do this. I'm on my 3rd TA for the dysfunctional box, the current one being brand new. I'm afraid to introduce a problem to my only functioning unit.

    Well, then, leave the TAs where they are and swap the TiVos around and see if the trouble travels.

    Either way you learn something.

    Unless your house is an unusually long way from the subscriber tap, that amplifier is unnecessary. Although there is no hard and fast regulation for this, the CATV company is responsible for delivering acceptable signals to your receivers in any "ordinary" situation. Two TV outlets and a modem is just about as ordinary as it gets.

    Look up the return levels in the TA diagnostics. That's why they are there.

    You already may be verging on too much loss on the return with 11dB splitter loss and 1 or 2 dB loss for the amp. An additional 6dB isn't going to help. If your signals levels are too high, get rid of that amp. If your signal levels are not too high, get rid of that amp. If your signal levels are too low, get rid of that amp and have the CATV company fix their signal level issue. (Again, the exception would be if your cable drops are quite unusually long - typically over 100m, including both house and wall drop.)

    I'm not quitre sure how to answer that. It is possible there is something wrong on the cable path - particularly the return - that does not affect non-SDV channels.

    Which merely means SDV is not working on that TA. Since the other TA is working, the likely culprit is either the TA itself, it's interface to the TiVo, or the transport system between the splitter and the TA. Note I said likely. There could be an issue which impacts the operation of the TAs to the extent that they are right on the ragged edge, and something about of the situation puches one TA over the edge. Reporting the TA return levels will help rule out that scenario or suggest it more strongly.

    I reiterate:

    1. Get rid of the amplifier.
    2. What are the return levels?

    Which means there is something different between the two. Duh. Reporting the transmit levels will help determine what.

    So I did the swap out with both tivos and TAs with no luck.. I decided to call tivo to see what they could do. I got a very helpful dude who called TWC and got us straighten out. Thanks for your help.

    Did Time-Warner give you an answer or explanation that you could make heads or tails of?

    OK. I got permission from the wife to get Tivo. Before I take the plunge, what is the current state of tuning adapter reliability in the Raleigh/Durham area? What should I expect as far as tuning adapter problems these days? It seems like maybe things had gotten better based on comments here and in other forums, but I thought it wise to ask.

    Thanks,
    Ted

    I guess no news is good news? I signed up for the win back deal yesterday. Install of the TWC whole house DVR is Monday. I'll pick up the cable cards and tuning adapters on Monday afternoon and hopefully have everything running by Monday evening. Friends tell me the TWC whole house DVR is as good as DirecTV's, but somehow I doubt that. I am only getting it to get the low price switch back deal. Either way, I will be saving $40-$50 per month versus DirecTV for the next 2 years -- or more as DirecTV continues to raise prices every year while my price stays the same.
