With the next-generation HD-DVD and/or Blu-Ray discs on the way, I'm wondering what older TV shows might possibly appear in high resolution (Not shows that can now be seen in high-def like CSI, Enterprise, etc.). There are a number of TV shows I would like to purchase now on DVD but the cost is far too prohibitive to get a complete set of TV shows in both DVD and later on in high-definition. (For this reason I now am limiting the number of DVD movies I purchase) So can anyone help me out?
