I applaud your efforts. As to your question, I'm not really interested in the video aspect, some are, some aren't. I generally listen to music or watch TV, not both.
As to your comment concerning older recorded items (Tom Petty/Neil Young) not being suitable for HD audio, I'd respectfully disagree. Yes it may not have the 100% of the benefits of the recordings you are doing tailored specifically toward HD audio, but to imply its a waste of time is not accurate either. Tell that to those who own and cherish a number of classic SACDs or DVD-A of such things as Pink Floyd DSOTM, etc. Many old classic analog recordings could get a real benefit in a remaster and release in better than redbook format. I heard Neil Young's BD recording at a friends and thought it sounded great. I rebought After the Gold Rush in HDCD, just to get slightly better than my current redbook version.
