The ESB DVD is ready to be authored and I'll capture ROTJ tomorrow night. Here's a sample from the set for anyone that's interested.
The capture is MPEG-2 480i, but contains 384kbps audio, not the 16bit LPCM audio that will be on the DVD: http://www.mediafire.com/?e92re06qdti3gz6

The ESB DVD is authored and it is 7.13 gigabytes. Now I just need to capture ROTJ and the preservation will be complete.
