Re: Blu-ray and HDTV
I don't know that I agree with Bacon12 on the video part (the audio part is obviously established). When I compare Casino Royale, the blu ray is significantly better than the same DVD upscaled (by the same player). In my case it is a PS3, and it does a good job on both blu-rays and upscaling from what I read. So in my opinion, the video output is substantially better on BR.
As for resolution, I would say try to find a 1080p set, as tests have shown BR to look marginally better on 1080p vs. 720p (I have only ever had a 1080, so I can't confirm this myself). Size would also matter. If your getting say a 32" or smaller, I don't think 1080p matters much...
