I was able to get a copy of the 1982 Kostal recording of Fantasia, and would like to mix it back into the video from the new Blu-ray. What would be involved in this? My thinking is:

Capture the video from the DVD

Convert to AVI (required?)

Open the AVI with an editor and add the 1982 soundtrack

Compress and burn to DVD with both the '41 and the '82 soundtracks.

Any suggestions for software are welcome. If anyone has Deems Taylor recordings, that would be great as well. Also, would love to share this with anyone, but is it considered a "custom DVD" by this forum? I tried to figure it out, but I'm not sure.
