I'm currently looking at the options available for HDTV. I'd like to buy one within the next four weeks. I've looked at the Toshiba RPTVs. I have a hesitation regarding RPTVs insomuch as the viewing angles. I've always been under the impression that these sets was out or darken if you aren't looking at them dead on. Any advice on an HDTV purchase would be great, but I do have these questions: 1) Does every HDTV do progressive scan? 2) What is the importance of DVI? 3) What additional features should I look for? 4) What are the benefits/drawbacks comparing RPTV with Direct view? 5) Which brands has anyone here had luck with? 6) Viewing distance (my big issue with my partner) I'm looking at a 50" but I've been told the room isn't big enough for a 50". The room is 18x8-10'. Any further advice, especially with regards to pricing, is welcome. Thank you.
