I actually received my boxset a few days ago, but I've been too busy watching it to write about it!
The good news is that the transfer is very, *very* good, having been made straight from digital masters. In fact, it probably looks better than when it aired on TV if only because an analog cable signal doesn't come near DVD-quality.
The bad news are twofold (for me at least): very little bonus content (no Medusa shorts for example), and a constant stuttering in the audio because of the way they adjusted the original 25 fps masters to play at 24 fps (thus a bit slower, necessitating a pitch correction like the original Season 4 DVD). I can't hear it in the dialog or the sound effects, but it's really obvious in the music. From reading
this thread, that's the way Shout! received the masters, so apparently Rainmaker is to blame for that.
Also note that season 4 is presented as separate episodes instead of movies and the audio for those is 2.0 instead of 5.1. Apparently, Anchor Bay still had the rights to that version so they had to go with the masters for the TV broadcasts, or something like that.
Depending on how obsessive you are about audio quality, this might either make you regret your purchase of simply annoy you slightly. I'm not that bothered about it since we finally got the first two seasons and they look great. And all in all, for a 17 years old show, it looks exceptionally good. It was also nice to finally see the uncut version of "Web World War" instead of the censored ABC version. And heck, to see all episodes uncensored. It took the Internet for me to understand why the audio would sometimes go out for a second or two while watching it on ABC: they censored all the farts as well as a few off-camera punching sounds. BSnP for your convenience/annoyance everyone!
