Being in Australia where HDTV is by far in the minority (long, bull **** story, don't ask, just hit up Wikipedia) but ever since I got the "House MD" blu-ray box and saw what a proper HD TV show could look like, I'm now what you'd call a complete convert! So I'm always looking at which shows were shot on film in the hopes of a bluray release anywhere in the world. "Cheers" is one I think could use another do-over just because it always looks so dark, although that could have just been the channel playing it. But because I like UK comedy shows the most, they'll forever be SD as they are a mixture of video for indoors and film for outdoors. As for Vidiot's claim of some film not having 4K of information in it, I thought at first surely not, at least not with anything made in the 1950's onwards, until I've remembered some Australian TV shows that were shot on Kodak film (late 1980's to mid 1990's) that look so grainy, I start to wonder if they would even have enough resolution to be made into HD? The shows I'm thinking of in particular are "Police Rescue", "Round The Twist" and "Heartbreak High", plus the shows "Water Rats" and "Stingers" are a bit on the grainy side too. Most of these are cop shows, with a couple of teenage shows thrown in. But I wouldn't be surprised if these shows couldn't be rescued (due to the film being gone for whatever reason) and we'll be stuck with old SD videotape transfers.
