Long story, but I have a load of old VHS home movies that I've captured to mpeg with an Adaptec VideOh! capture card. The mpeg files are all fine EXCEPT for the minor problem of the sound track which is in the left channel only, and sounds odd when played over a surround sound setup... Trouble is all the kit (capture card, video camera, decent VCR machine, etc) has all gone back to it's respective owners so I can't re-capture it again. The obvious fix is just to copy the left channel into the right (as it was all mono anyway), but I can't find any software to do this. I tried with VirtualDub, but I get a "No video frames found in this file", playing the files with VideoLanClient plays them just fine (and it can play the sound correctly), and producing a DVD works fine too (apart from the sound), so the mpegs shoudl be OK. Sorry for the rambling, Any ideas?
