TiVo HD units are receiving another software update today, moving from 8.1.7b1 to 8.1.7b2
If you have a TiVo HD, check your Messages & Settings -> Settings -> Phone & Network screen. If it says ‘Pending Restart’ then your box has the new software. If not, then ‘Connect to the TiVo service now’ and it should download it. Once it says ‘Pending Restart’ go to Messages & Settings -> Restart or Reset System -> Restart the TiVo HD DVR to force a reboot, and it will install the software.
You don’t have to do this – it will automatically download it the next time it calls home. Then install it at the next 2AM window after that. This just helps you get it faster.
No word on just what it is – but it is a safe bet it is meant to help address the macroblocking issues. However, doing a spot check of my unit with the new software I’ve seen a couple quick flashes of macroblocking, but it does seem to be greatly reduced from the previous version. I’m not seeing the regular, severe macroblocking I was seeing before. First impression is that this is a real improvement. I’d love to hear what other people think and how much improvement you’re seeing.
I dropped an email to TiVo to see if they have an official statement on this update.
EDIT: TiVo responded to my email by referring me to a post on TiVoCommunity.com from TiVoPony:
As promised, here’s an update on TiVo HD.
We’re releasing a new software update later today for TiVoHD, you should see this download to your DVR over the next day or two. While our original update resolved issues for many people, this new update addresses some of the additional macroblocking issues people have reported.
Please continue to post and let us know if your issues persist following the upgrade (you can also post if your problems go away).
We will continue to work through any additional issues that are uncovered. We appreciate your patience, as well as the valuable feedback you’ve all provided.
