When I play them back on my newly built Win7 x64 WMC they tear and pixelate badly. SD is OK. I have driver version 18.104.22.16861 installed.
I'll be watching this thread closely to see if there is a resolution. Can't really put this new HTPC into production until Recorded TV plays back OK.
Thought: If you install ffdshow, is there away to use a different decoder than the MS-DTV one inside WMC?
Robin - when u say "MS-DTV_decoder + VMR seems OK" what does 'VMR' stand for?
VMR is the 'old' Renderer, which normally no one uses anymore. EVR is the newer one which is used by WMC. I don't think you can easily hack WMC to use other decoders/renderers, at least not for live-tv. There were threads at hack7mc that showed how you can try the pdvd decoder (32-bit only). That one also seems to be the only one that does what wmc expects from a live-tv decoder (probably some DRM stuff and other things (e.g. spanning events)).
BTW, I just got an email from someone claiming that it works for him on a Intel Q77 board with a 3770s processor and 16 GB 1333 samsung RAM.
I can't check right now, but the difference to my system would be the memory (I have 1600 XMP 9-9-9-24 memory) and the processor (he has the 's' type). I don't think the processor is the issue, but memory maybe. When I get home tonight, I'll try using the slower 1333 memory profile and see if that helps anything.
Setting memory to 1333 didn't help, neither did removing 2 of the 4 dimms, nor the latest win8 driver...
I hope the guy who says it's working continues to help analyzing why he doesn't have the problem.
you can always go the software only route (switching off dxva altogether). I would rather use SB instead, if that's the new idea of 'green' IT.Edited by Robin Mitra - 8/21/12 at 1:06pm
