YouTube versus DVD
It's convenient to watch episodes on YouTube (which currently has the Longstreet pilot plus all 23 eps, at least one copy apiece), but is it the same as playing a DVD? Here are my thoughts, would love to hear yours.
Video quality: I've never done an A/B comparison, but my impression is the DVD has better resolution.
Sound quality: No idea. I can generally understand both. Presumably the DVD is at least as good as YouTube!
Subtitles: The DVD that I have (the one whose cover is shown on the main page here) has no subtitles whatsoever. YouTube has subtitles, but they're computer generated, meaning that although most of the dialog is accurate, quite a few bits are ludicrously wrong. They would presumably be useful for someone whose hearing is worse than mine, or who needs to watch with the sound turned off, but I generally find them distracting, so I turn them off, using the "CC" (closed caption) button.
Completeness: It just occurred to me that many (probably most) of the YouTube videos appear to have been recorded from television broadcasts, and it's possible that the broadcasts had been edited. So I added up all the time lengths shown on a YouTube play list (plus one episode that's not in that list) and compared the total to the time shown on the DVD back cover. (Note: YouTube has multiple versions of some episodes, and my figures reflect only one of each.)
The YouTube total is 55 minutes shorter*, which sounds pretty bad -- but that's only two or three minutes per episode on average, which could simply mean that they're missing a bit from the beginning of the opening credits and the end of the closing credits -- and/or that the time reported on the DVD includes a bit of leader and trailer -- and/or, yes, it could mean that some actual scenes were trimmed.
Bottom line: If you want to be reasonably sure of seeing every single bit of an episode, the DVD is presumably your best bet. If you need subtitles or just want to relax at your computer, YouTube might suit you just fine.

*The playlist that I used includes episodes posted by three different people, and the very shortest was the only one posted by that person -- but the other two posted a mix of shorts and longs. The YouTube times vary between 46:35 and 49:21, with the great majority (15) being in the short stretch between 48:03 and 48:22, four between 46:35 and 46:56, another four between 49:00 and 49:21 and absolutely none between 46:57 and 48:02 (quite a gap!) or between 48:21 and 48:59. It's possible that most of the episodes were actually filmed to be 48 minutes long, but a few were filmed to be only 47, and another few to be 49, perhaps reflecting changes in network requirements or FCC regulations.
