A friend of mine had VHS copies of every Battlestar Galactica episode ever made that he recorded as they first aired on TV! Unfortunately, he passed away about six years ago, and I have no idea what ever happened to all his stuff.
He also had the entire Showtime original series of Bonanno: A Godfather's Story, from when it actually aired! All 360 minutes of it, uncut and unedited. I sure wish I had a copy of that right now!
