From ffdshow I am using "Resize" to "PC resolution" and I am using Post-processing with the default settings. It looks GREAT on some DVD movies, others (especially where a lot of movement is involved) it stutters and eventually stalls completely. The odd thing is even if I disable all of these filters it still stutters when using ffdshow for playback. If I select MPC or Microsoft DTV-DVD it plays better, but looks awful. I tried enabling ffdshow as a post-processing filter but that did little to nothing compared to using it as the player. One weird thing I've noticed is that I am able to select ffdshow DXVA for h264 video but NOT for DVD so I assume I am not getting the benefit of HW acceleration. Any idea why I can't select the DXVA version of ffdshow as my DVD codec? Is it not possible? edit: Uh, as usual I found a solution by pressing random buttons. I uninstalled ffdshow and re-installed it, this time making sure I had selected to decode MPEG2 during the install. Now the ISOs play flawlessly with the upscaling. edit2: I spoke too soon ... problem is better now, but on certain DVD-5 ISO files/directories ffdshow just CHOKES. This seems to be limited to certain older DVD-Rs I have (may be a problem with DVD-Shrink which I was using at that time) so I believe it's a rip issue. However I can play these ISO back fine in VLC Player (albeit at lousy quality). I think I'm going to try alternate DVD playing Codecs later when I get home from work. Anyone know why I can't select ffdshow DXVA for Dvds? Not that this would solve the issue necessarily, but I would like to try it. edit3: Look like SAF may be the answer I'm looking for as it says it supports DXVA for Mpeg-2 which I think is my whole problem. [url=https://forum.team-mediaportal.com/codecs-331/saf-v5-02-final-based-ffdshow-dxva-decoder-77591/index295.html ]Link[/url] Will try it when I get home. edit4(final update): After testing nearly 50 DVD-ISOs I have only seen this problem on two of them, so I have concluded it was a rip problem of some sort, not a codec problem at all.
