Hi All, I have exactly the same problem in transcoding the RMVB files. It seems that Mencoder does not like these files at all and I guess we'll have to wait for better support.
or somebody else has an answer how to solve this? With ffmpeg? Avisynth?
If not, I will convert these files into regular avi's, but I have 100s of these, so I prefer to have a better solution before starting
