Problem with 1080p Playback

Just a quick suggestion, have you tried different renderers? I remember I had this problem with laggy playback and tearing on my old setup, I think I solved that by using the EVR render (on XP SP2, it is explained in a thread somwhere here how to use it on XP).

Thanks for the suggestion. I tried VMR9 and EVR rendering and there were no significant changes in the video lag. Mind you, the lag/jitter is small to begin with, but it's nonetheless annoying to watch a movie that jitters even for fractions of a section every minute or so.

I've also tried a variety of the decoders and none of them seem to work. Not only do the video files play correctly on MPC, but also on MediaPortal, but that was too buggy so I switched to GB-PVR. I really want to know what's causing this lag, it doesn't make much sense to me.

Do you have any other processes running that is cpu- og disk-heavy in short bursts? Like some tray icon that monitors som kind of status or anything like that?

What's your CPU % when playing? You need to make sure the codec being used is taking advantage of hardware acceleration.

I have had the same problem. I found it was better once I told ffdshow not to handle mkv for video (but left for audio), and switch to coreAVC.

The problem is I like ffdshow to handle subtitles, because having vobsub and ffdshow both installed sometimes causes dupe subs. I need to find a way for vobsub to only kick in on mkv (or just have vobsub handle subs for everything).

Well I have tha same problem with double subtitles, I just turn them off in FFDSHOW, but it's a bit annoying, so I would be interested in a more permanent solution...

Hi, you said it was better, so I assume it did not solve the problem?

How do I make ffdshow to not handle mkv videos?

Anyone have any other things I can try? Thanks.

No, it seemed to fix it. I made a custom filter for video that said if the file was mkv, then don't use the 264 hndlers. It also turned off resize and subs. But, since I need subs, I still use the handler, and just watch 720 for now. I plan to try to figure out how to get vobsub work better next month when my wife and kids are away (and can spend a few hours on the tv).

Still, I find it strage that that little extra processing would throw it off so much.

I did finally get my chance to play more, and it did help a lot.

In the end, I decided to take ffdshow out of the equation when it comes to video. Their x264 support wasn't quite good enough yet. I opted to use coreavc instead. The newest version has support to use nvidia HW in most newer cards that dropped the processor overhead to 10% on a 1080i sample (40% w/o).

That said, it wasn't as crisp as it was w/o the HW setting on, so I'm leaving it off for now. It introduced some blockiness that wasn't there before, and since I'm not playing 1080i files yet, I decided I could wait until they perfect it more.

To handle subtitles, I added directsub. That works very well, except I had to tell the splitter to load it (it wasn't being auto-detected like w/ xvid, etc files). I don't know if it is better than ffdshow/vobsub (although I think their's may have been just a little crisper in non-x264 files), but subtitles was the only thing I was using ffdshow for w/ x264.

I still use it for x264 audio, and for all non-x264 files.
