Actually, there was no 97 SE HD broadcast. And I think Wookiegroomer released some BD sized versions of the 2004 SE with some basic colour correction. The thing is though that the largest HDTV capture of SW available is under 20GB, so blowing it up to BD is kinda pointless. If you're looking for a larger sized file, there is Ady's ESB (which is a colour corrected reconstruction of the 97 SE) as a 16GB mkv but I don't know about anything else. But believe me, a 50GB BD is a really pointless download right now.
