Could this difference be related to the graphics card ? |

On the other side, MAYBE the link below "x264 Encoding Options for Hardware Compatibility & DXVA", pointed by @MatMaul should be reviewed considering Hardware by Hardware. Over here (with 8600 GTS) I can not have sucessfull DXVA with more than 4 Ref frames, even for very low resolution like 704x396. Quote:

G80 nVidia GPU's like 8800gtx only support motion compensation (DXVA1/XP) wile G92 GPU's like 8600gts or 9800gtx support bitstream (DXVA2/vista (or xp+evr)), i.e. full video decoding. MPC internal decoder only supports bitstream.

I have same problem on nvidia 9600GT. Previously i had HD 3200 integrated on 780G chipset motherboard, and before than i haved HD2600XT AGP on older machine. Both radeons decode fine with DXVA support, on every video render (VMR7/9), with both MPC-HC or Cyberlink H264 decoder's, never have problems with drivers and similar. But with nvidia 9600GT, first time when i installed driver, playing video in MPC show corrupted frames, than i update to lastest drivers found on nvidia site, now cyberlink decoder work fine, but MPC-HC return me gray screen, and there is no playback. I want just to say nvidia's prue video is suck comparing to radeon's UVD. I don't know why ppls love nvidia.

This topic is a bit messy. May I suggest the following to the regular posters here:
Someone (with a DXVA capable graphics card) should open a new topic for discussing these "DXVA compatibility" issues. The opening post of that topic should be updated on a regular basis to contain a summary of the content that is discussed in the topic. Contents of this opening post could be: * Links to sample files. For each file technical details (levels, max ref frames, etc) should be included. * A list of graphics card models that are (somewhat) compatible. If a card has some limitations with regard to the type of files that it supports, then that info should also be included. * For each sample file, maybe list which cards are able to play it and which are not. * The rules for getting DXVA playback: compatible card, H.264 bitstream requirements, no intermediate filters, etc. * A FAQ that answers frequently asked questions and gives solutions for common problems.

It does not seem there were any comments on this. Is it possible that this could please be fixed? I have just remuxed Elizabeth - The Golden Age on HD-DVD (VC-1) and it actually has noise (flashing white blocks) in the extra 8 lines. In PowerDVD the original disc does not show these. Even TheaterTek does not show them playing the remuxed mkv. However, MPC-HC (still using the official release, not any beta, don't know if this makes a difference) shows these last 8 lines, which are never meant to be shown on any hi-def disc. I know I can manually move the picture down "one notch" and get rid of the extra lines, but this is messy to do with every hi-def disc. Like CoreAVC, could there be an option to crop 1920x1088 to 1920x1080, for AVC and VC-1? Thanks |
