FYI for the undecided: The TIH season set discs are all single-sided (so far) and in those nice, space-saving slimline cases. Season 2 is using the 2-disc double storage slimline cases, further reducing wasted shelf space.
As far as Universal going back and ponying up the dough to pay for digitally re-storing the episodes (I assume you meant restoration - sharpening, removing dirt & grain, adjusting color, etc.)... well I wouldn't hold your breath. Universal is notoriously cheap about paying anything but the bare minimum need just to get the films ported over to digital format for DVD.
There are so many wonderful shows Universal has in their library, but they have rarely done much of anything to give fans the extras we love and crave so much. If Kenny Johnson hadn't done his three commentaries for FREE we would've had the typical 'barebones' releases normally seen from Universal. Quite sad, really. I also am collecting "Emergency!" by season, and despite the fact that the two main actors are still alive and well, (along with many of the extended cast), Universal hasn't included any of the supplementary material they should: interviews, commentaries, behind the scenes, old home movies, promos & tie-ins, intro bits & next week's clips, etc. etc. Absolutely NOTHING. It makes me angry and sickened at the same time, yet I find also find myself just being thankful that the shows are being released on DVD at all. Ugh.
Same thing about "The Six Million Dollar Man" in this case. By the time Universal works out the legal BS to get it on DVD, everyone involved will probably be dead! Friggin' cheapjack weasels.
Maybe if TIH TV series is someday cut on the HD market we'll see restored hi-def versions - but don't bet on it.
