To bring this back on track, the OP asked about capturing the analog outputs of a 622 and mastering Blu-ray discs with that content. My original reply was, "More trouble than it's worth, and here's why..." Watchel, with your level of money invested in your HT system, I don't think you'd be satisfied with the results, either.
If there was a way to move the MP4 files off of a 622, chop into it chapters, fabricate a transport stream around, and press it to BD-R, that might be worth it...Except that Dish already compresses their streams to bitrates low enough to fit on a DVD-DL. Even if it worked, which we wouldn't be talking about on this forum, there are cheaper, more portable ways to get your content, though even less legal.
To the people with R5000s, I'm jealous, at least I think I could be. To the people with 73" 1080p sets who sit less than 7' away, I'm definitely jealous. I just hate to see people buy prime rib when a cheeseburger is more nutritious, just as filling, and would have been as satisfying.
