is there a better way......

Hi. I captured, via a Canopus ADVC 100, a documentary from a PAL VHS that I taped some 20 odd years ago. Rather stupidly, I failed to connect one of the audio cables and, consequently, I only have audio on the right channel. As it is a pain to lug down the VCR and recapture the footage, I was wondering whether this workaround works or is there another better or simpler method? I plan to extract the audio from the raw captured avi using Virtualdub and only extract and convert the right channel to wav format. I have already done this and it appears, when I play the wav file back, I now have audio on both channels. I would then load tmpgenc 2.5 plus (the software I use for encoding to DVD compliant mpeg 2) and take the raw avi file as the video source and the wav file saved by Virtualdub as the audio source, I would then author the resulting Mpeg 2 using DVD Author Pro 2. Hopefully, by extracting and converting only the right channel (where there is audio) the resultant wav file would have audio on both channels. I tried encoding, via tmpgenc, the audio in the raw avi to mono and dual stereo, but for some reason the resulting file only had audio coming in from one channel. Any comments please?

I don't use TMPGenc so I can't help you there...but...

Download and install Audacity: http://audacity.sourceforge.net/

Open the WAV file that you have extracted from the AVI with Audacity. On the left there is box with the track information. If you have two tracks (which you should) Click the little arrow pointing down and select split audio tracks. Click the X on the track you want to remove (the blank one). Click the box to the left anywhere to highlight the entire remaining track. On the top menu select edit>duplicate. Note that it will say right or left in the box to indicate what channel the track is from. Click the arrow on the new duplicate track and make it the opposite of what ever channel the top one is. Go to File>export as wav.

Go back to VirtualDub and from the top select audio>WAV and from the dialog box select the wav file you have created in Audacity. Select the video>direct stream copy... And finally file>save as AVI
