I use a WinTV PVR to capture MPEG2 files which I then edit the commercials out of in Womble. However, about thirty seconds after each cut, the resulting video gets choppy (5-10 fps) and the audio desyncs. Any one have any ideas? Should I be remuxing the video from the PVR before editing in Womble? Remuxing after editing? Any help wouble be appreciated.
