Curious to know if anyone has this cracked now. I had no problems getting full Hardware Acceleration on HD .mkv files, but once I got a satellite card neither MPC-HC or Cyberlink PDVD8 could accelerate the H264 .ts files (in an mpeg container) used by BBC HD, ITV HD, and Luxe TV HD - at least not with acceptable results. Would get bad interlacing and strange stuttery play.
So I settled on CoreaVC - because it works - though it does have it's own quirks, notably not seeking through .ts files so well. Play usually freezes after a ff or rw skip, and you have to press RW - FF a few times to start play again.
I could not even use the hardware deinterlacing with CoreAVC, because it would stop deinterlacing working properly. Downside of this was typical 60-70% CPU viewing the HD channels, thus noisy fans. This was also the reason I chose not to use MPC-HC or Cyberlink decoders without HA - because the deinterlacing was not right.
The reason for me looking at this issue again is, firstly, because I saw a post by user 'Adspence' saying that a newer version of CoreAVC fixed some issue - so I installed CoreAVC 1.85 and, sure enough, hardware deinterlacing now works perfectly - if NV12 is selected as the output colourspace (the NV12 option is new) - This alone has dropped CPU to 45%.
Secondly, for the the first time, I managed to get perfect playback (with no interlacing or stutter) of GBPVR HD recordings, with HA, in the MPC-HC stand-alone player. To achieve this was just trial and error, but the the following settings (image attached) - and only these settings - plays perfect HD with only 10% CPU. Any deviation from these settings - for example using 3D surfaces or YUV mixing - and play of the files becomes unacceptable.
Using the MPC-HC stand-alone decoders, or Cyberlink PDVD8, in GBPVR results in no HA. Looking at the filters used during playback, the only difference I can see is that MPC-HC is using the Halli media splitter, and PVRX2 uses the MPEG-2 Demultiplexer. No idea is this has any bearing though...
