I had successfully converted many RM video files using EO-Video, WinAVI and AVI2DVD, but I still had no success with conversion program which take care of stereo channel audio extraction of dual language video files.

For these special files, usually I had to resort to rip video (to avi) and audio (to mp3) separately, manipulate the audio using tools like Goldwave to single out the channel, and duplex it to the other channel, and then merge the video and audio back using tmpgenc to mpeg2.

Tedious if you got over dozens of such files to encode.

Is there any apps I can use which does above in one-easy-go in batch mode?
