Hello all,
I'm hoping someone has already tackled this problem and found a cause. I'm using a wired MVP to extend my 2.0.3 NPVR box to the bedroom. After a bit of tinkering, the MVP is booting and loading fine. Also, all of the menus look normal and fit on the screen (4:3).

I'm using a WinTV-HVR-1250 (http://www.newegg.com/Product/Product.aspx?Item=N82E16815116024) to record NTSC and Clear QAM. Both can be recorded and viewed without issue on the host computer.

When viewing recording on my MVP, analog NTSC recording come across fine while those recorded over the Clear QAM channel have some issues. I performed a test - playing NTSC, 480i, 720p, and 1080i.

NTSC - clear playback with sound.
480i - clear video, clear sound, but out of sync
720p - no video (black screen), choppy sound
1080i - no video (black screen), clear sound

I've attached my logs and config.xml for the test session. If anyone has a few minutes to take a look, I sure would appreciate it.

Approx. log times:
11:07 startup MVP
11:10 NTSC video (MythBusters)
11:12 480i video (Katie Brown Workshop)
11:14 720p video (Religion & Ethics Newsweekly)
11:16 1080i video (Pearlie)
11:18 MVP to standby

Thanks

Those results are expected. The MVP can't do HD video and there is no mechanism in mvpmc to keep AC3 audio in sync. You would need to pre-process these to mpeg-2 SD video with mp2 audio, which generally can't be done with a universal command line to any utilities I have found.

Just to add to this, you could also invest in a refurbished PCH A110's ($105) & then you can play your HD videos without having to pre-process them, it also has the added advantage of the interface being a LOT more snappy than with the old MVP's....

That looks like a great option. I think it's finally time for an upgrade. Thanks for the link.
