XP Media Center version is what I have, I think having media center is a Tversity requirement. Again the boys took the xbox360 which give you a menu for TVserity and you can watch many video/movie formats on you PC via >Tversity>Xbox360>TV. I think I have watched over a 100 Netflix movies streamed to the Insignia Blu-Ray DVD player hooked to my Plasma HD TV.
Two things are missing with the streaming from Netflix, you only get 2.1 sound, I hope when 5.1 becomes available later this year, the bandwidth requirement won't be to heavy for my 3M DSL connection. The other is subtitles, my wife refuses to watch a UK or brit movie without subtitles, even some American movies she prefers subtitles because some people are really hard to understand. Foreign movies with the subtitles already in the movie are fine, it is when the TV has to decode the subtitle data stream, which is NOT streamed via Netflix. Netflix will be streaming 1080p later this year, again along with the 5.1 sound I might have to switch to cable for internet.
