Suddenly .mkv playback problems
Hi,
a few weeks ago I watched some videos which were in .mkv format, here the overview: Video: MPEG4 Video (H264) 960x720 23.98fps Audio: AAC 48000Hz stereo I had no problems playing them back in Media Player Classic, everything worked fine. A few days ago I wanted watch the videos again but now at certain points the player skips a few frames ahead. It doesn't look random too because it always skips at the same fime. Tried it in VLC too but when the point appears the player just crashes. I didn't make any real changes to my PC - exept some video card driver upates. But I dont know which one I had at that time... Windows XP AMD Athlon 64 X2 3800+ Nvidia Geforce 7800 GTX Hope you can help me out here Edit:/ I disabled all excisting codecs on my PC via MMView but still the same problem. while watching the CPU usage is just around ~30% so cant be that my CPU is too slow Edit:/2 this is the log I get out from VLC, but nothing that would help me. Is there a way to debug MPC and/or ffdshow? Maybe they show something up. Couldnt find such options or sommands the main error appears until the first "mkv error: invalid track number" in the log. The stuff after that just happens if I leave VLC running so it tries to play the file back again. Code:

yep, I did disable the proper internal filters and imported ffdshow, the ones from Nero and CoreAVC trial (although this one isnt really for that format I believe?)
Now tried the "The Core Media Player", but just happens the same thing. Skips a bit, gets blocky/pixelated and then back to normal at the exact same scenes |
