Hi All
I am capturing my old VHS tapes, with the help of a dv camera, connected to my pc through firewire.
I am using winDV to capture the DV data.

My problem is, my VCR has only one audio channel, but the data is captured as stereo, so I can only hear sound in one channel (left in my case).
Since I have many avi files, I'd like to do the conversion (drop right audio channel, and create a mono avi) automatically. I was thinking of avidemux, ffmpeg, or mencoder, but I could not find the right way to do that.

Currently I am doing the following
1) save wav file using virtualdub
2) drop right channel, and make the wav mono using Auducity
3) replacing the stereo audio track with the new created mono wav from step 2, using virtualdub again.

I am familiar with both XP, and linux (ubuntu in my case), and I'm also familiar with shell scripts. Is there a tool I can use to do all that in batch ?

thanks,
popo
