I have a WMV8 file I wish to encode to mpeg, but the two encoders I have tried seems to choke on the file after a little while. Therefore I want to force them to use ffdshow instead of Windows native codecs to play this file. Is this in any way possible? I've configured ffdshow to use libavcodec on WMV2/8. Could it be that ffdshow won't take command over the file since it has WM9 audio?
