I have the Motorola 6412 from Comcast in Seattle. They had moved to the 12.35 firmware which caused loads of problems. The worst of which was the random reboot. I finally (after much trouble) got them to give me 12.31 back.

12.31 is not with out problems. Non HD channels and recordings seem to lock up when I try to fast forward. And I get video drop outs when going from an HD channel to a regular channel.

I know that Motorola has released firmware up to 16.35. Does anyone know what the latest firmware Comcast is offering is? The 12.31 firmware is annoying but livable, but if they've fixed the issues that plagued 12.35 I'd like to upgrade.

Also, anyone know if/when the Tivo software will become available?

I have the same issues with 12.35 and am fed up at this point. I will be calling Comcast to try to upgrade or revert, anything to get off this broken version. I'm hoping someone else will chime in here...

I have Insight cable in Indiana, and my 6412 has (as of last week) firmware 16.35. My previous firmware didn't support HDCP routing, which means it was 12.31 or earlier. Now I can finally run hdmi through my receiver!

If you call your cable company, and get somebody on the phone who knows what firmware is, you may be able to see if they have any plans for 16.x.

There's some relevant stuff at http://en.wikibooks.org/wiki/How_to_use_a_Motorola_DVR/Firmware_and_Software

They sent me a 12.31 firmware update which resolved the random reboots, but FF and REW have a lot of latency now and it introduced a fair amount of other annoying issues. Recording reliability seems worse, with some recordings freezing partway through... At least it doesn't crash though ;)

Give it time. There'll be more HD material coming the more people adopt it.

And let's face it, the actual HD stuff (discs and programming) kicks ass imagewise.
