For sure, laserdisc has the audio commentary not found elsewhere; for the other contents, I have not found further info to know if the DVD first three extras are actually the same material found on the laserdisc commentary...

These would be great. But I'd still want to go for a HDTV 1080i master, not from the Blu-ray. As I've mentioned all the non-audio extras should be grabbed as mid or low bitrate AVC. I'm still interested in this too. Use the X9, of course, with the LD. X9 should be used with all your LD grabs anyway.
