barrett14, in case the URL above starts you with post #41 being the top of the page (which is what it did for me), you're looking for post #40.
Everyone can have a different "posts per page" display setting, which can cause people to land in different parts of the thread when clicking on URLs that refer to specific pages.
Very true, and very often overlooked.
I have my posts/page set to the max, not the default, PLUS I have the highest numbered post first (listed in descending order). So every time somebody says below/above, it's the opposite for me...
I am a Charter Cable Customer in Sunny Southern California (San Gabriel Valley) and am also running a Cisco CC at 1.5.2-Fp.2401 (I think all Charter Cisco cards are at this firmware release), Charter still uses a TA.
I set my Tivo Roamio Pro up for 5 tuners to correct the V58 errors about a month ago and have had zero tuning problems since that change.
It would be nice if Charter would come into the current decade and upgrade the firmware to the current release (1.5.3-Fp.1101??? ) and eliminate the TA altogether, as far as I know Charter is all digital now so I don't think there is a real need for the TA anymore.
I am adding a total of 4 Tivo Mini's to my system, but I have stopped at 2 right now. I will add the 3rd and 4th Mini when I am able to use all 6 tuners on the Roamio.
I am still very pleased with the Roamio Pro, it is a HUGE improvement over the Cisco DVR's that Charter offers even with only 5 usable tuners.
From another Post to change the number of active tuners on your Roamio:
Go to Settings > Channels > Channel List
and enter one of the following number sequences using the number buttons on the remote. This will tell Roamio the how many tuners it can use.
- 88633 = use 3 tuners
- 88634 = use 4 tuners
- 88635 = use 5 tuners
- 88636 = use 6 tuners
Then force a reboot of the tivo:
tivo >> settings >> help >> restart
I had to give up two tuners, but so far no more V58 errors on the Roamio+. Now to get charter to up-date the cc firmware.
So is this issue with the Charter cable cards and not with the Tivo? Why is Tivo tech support blaming the signal strength and/or SNR on this?
Here's some "tech-babble":
All I can tell you, for sure, is that TiVo measures (calculates) SNR in a way different than the rest of nearly all related industry/companies. Also, rather than measure Signal Strength in dBmV, like the cable companies, and most others do, they use a 0-100 scale, where 100 means 0 dBmV, or higher (positive) value, and anything lower than 100 is something that would be a negative dBmV value (negative is not bad, in dBmV terms, until it hits a threshold, which varies).
If they'd just stick to the standards that have been in place for a long, long, time, which nearly everybody else uses, we wouldn't give the impression that all TiVo users are idiots, when saying "we need 36 or less SNR". If TiVo measured/calculated in the way nearly everybody else does, "the higher the SNR, the better" would be true, as it seems to be with everything except TiVo.
For a non "tech-babble" explanation, and a better answer to your question, do some reading here, and in TiVo's knowledge base section.
I'm sure somebody will come along, and give you a more direct, and less technical explanation, than I did, and/or post links to direct you to posts and KB articles that better explain this. I don't have them bookmarked, so I can't, without hunting them down again. Sorry.
In a word Yes! The Cisco cable card firmware is outdated and needs to be updated to the current release by Cisco. That will not happen until Charter finishes their approval process and sends out the update, (Could be a very long wait).
I have found that most support personnel (TiVo and Charter) are not current on Tivo problems like these and rely on the script they follow while trying to diagnose your problem. The 6 tuner problem being caused by out of date CableCard firmware does not come up as a diagnosis... Most Field Techs go through similar "canned" steps when they come to your home to try and "Fix" the problem, and are not aware that it will not be fixed unless the Firmware is updated, something they can't do anyway... At least they do usually eliminate any other possible problems while they are there with your cable service.
When I first reported the problem, Charter Service was convinced the problem could not be the CableCard at all... They swapped out 4 TA's, ran separate drops from the outside, bypassed my internal cabling, eliminated the cable pass-thru on the TA using a splitter instead, verified that that signal strength was good at all connection points. It wasn't until they (Charter) and I both started doing Internet searches and found articles in the Tivo Community describing the problem and recent solution that they finally concluded that the Cisco CableCard Firmware needed to be upgraded.
Is it possible to buy an updated cable card on your own or is the only option to wait for Charter? How will you know when Charter releases the new firmware?
p.s. - I reduced my tuners from 6 to 5 but its still doing it. I have not tried 4 tuners yet.
You have to wait for charter (or bother them) for them to get on the ball. At least one person here has bought a card off ebay, but they are not generally available and more importantly your cable co probably won't allow/install it on it's network.
Make sure you restart your Tivo Box after changing the number of active tuners. The change will not work properly without a restart.
Even if you do get a "Aftermarket" CableCard to work, once the Cable company sees it on their network they will automatically install the Firmware they are using, in this case the Firmware would be downgraded.
I have not seen it yet, but it is my understanding you will see a message on your Tivo the CableCard is being updated. Of course if this process occurs and finished while your asleep you may never know the update has occurred. You can go into Setting and view what Firmware release you have at anytime.
Well I hooked up the new Tivo that they sent me... Immediately had V53 and V58 errors again. I switched the numbers of tuners to 4 and now its working... We will see if it stays that way.
I don't know why Tivo wasn't prepared for the fact that Charter doesn't have a 6 tuner cable card? Not once did Tivo tech support say that this could have been the issue.
The cablecard is multistream and can decode 6 channels at the same time. The problem is the firmware that Charter supplies is not the latest and does not work properly. This is not a Tivo issue. Tivo does supply a temp workaround by at least allowing you to disable the tuners.
I'm pretty sure that was built into them the day they started selling them.
Then when it became clear it was necessary, they posted the remote sequences to use that "workaround".
TiVo was likely hoping for the best, but expecting the worst. Good thing they had that contingency plan in place.
The time between first reports of the problem, and the posting of the sequence codes was too close for it to not already be in the software, IMHO.
I have been dealing with these V53 and V58 errors since I bought this thing on the day it came out. After calling Tivo numerous times, they kept blaming it on the signal strength... It took me digging through these forums to figure out that my cable card couldn't handle 6 tuners. Tivo should have tried this fix with me when I called them.
Is there a way to definitively confirm whether or not the cablecard/company can support 6 tuners?
I've had 5 shows recording and able to switch live tv channels with no problems, indicating that I can do 6 tuners.
However, I'm plague with random, but frequent (~60%) v58 errors when changing channels.
I can switch up and down a few channels, and 'sometimes' the v58 channel(s) will tune right in. It's on both premier, regular, HD and non-HD channels across the board.
I'm just about ready to box all this up (roamio plus and 3 minis) and go back to the dreaded comcast dvr boxes. (At least I could reliably tune a channel)
Has reducing tuner count helped out at all? If so, I'd think that would confirmed it. I also have v58 issues. However, for me, it pops up after being on a channel for a while.
V58 error this morning trying to watch A Christmas Story on TBS !!
Can't wait for the C133 error to show up later
Merry Christmas Tivo !
No reducing the tuners does not help at all. I'd say a good 60-70% of the time, I get v58's on various channels.
I've got to say, I'm about fed up with all of this. As much as I hate Comcast DVR's (especially the old SA's we're stuck with in our county) I never had a tuning problem with them.
Yep never had a tuning problem with a SA box .
It's a shame they are awful otherwise
