Hello,
Hopefully someone out there can give me a hand with the following issue as a few hours of head bashing and google mashing was unable to solve said problem.
Basically, I am attempting to playback a VC-1 encoded file that has a frame rate of 29.97 (NOT 23.976) according to mediainfo, in MPC. On the whole, Splash Pro does a nice job, but has a few issues with audio staying in sync. Unlike Splash pro, Ive noticed that MPC outputs at a seemingly variable frame rate on this particular file leading to a gut-wrenching judder and a lot of dropped frames. Furthermore, these frames seem to be in the upper reaches of 43-55 fps, but never 60 (which would double the intended framerate and do just fine. They also are not at a locked 29.97, dissimilar to my many other h.264 files that lock in at 23.976 +- a few ms.
Thusly, I've deduced the issue to be one of getting a variable pulldown that isnt even as nice as 3:2. Correct me if that doesn't make sense or is incorrect.
Finally, I am using reclock (also tried without), the EVR renderer (have tried many others), vista aero on and off (tried both), and a quad core q8200 with 4gb ram, nvidia 260 etc. etc. Also of note I am streaming via usb-2.0 from an external hard-drive. However, no other blu-ray files in the h.264 format had such an issue, so i dont think its bandwith. Im transferring one to an internal drive just to see. Will post if thats the issue.
The only variable that may be a cornerstone to solving this problem, is the graphics card and turtle beach sound card have had other syncing issues in the past. New 6870 on its way Wednesday :) Needless to say, XBMC plays files beautifully. Unfortunately no interlaced VC-1 there yet :(
So the whole goal is basically to lock MPC into 29.97 fps, or even better, just get it to work properly without forcing the issue.
Anyway, if any bright minds out there can sift through the above info and shed some light on the problem it would be much appreciated. If you need more details please let me know, although I attempted to be thorough.
Regards,
Travis
