I believe that this has been discussed before but I have a huge DVD collection on my computer stored on several HDDs. I would like to convert them over to be streamed through my Xbox 360 (3 of them - older not new slims) onto 2 older TVs and one new flat screen. What I am looking to do is 1) save space on the HDDs 2) not lose too much quality 3) be able to watch all through the Xbox. I am eventually going to get a blu ray player so I am also looking into being able to use that to stream so the format must be compatible with both. What is the best format to use to accomplish this and what software do you recommend? I would be prefer free if possible but don't want to spend too much money.
