I have about 100 or so DVDs that I am looking to digitize onto my computer and then stream onto my TV via Xbox 360 or even with a media streamer. I am lost when looking for a way to back up my dvds onto a hard drive without losing any quality or the surround sound tracks. I don't mind if the files are 4-5GB the most important thing to me is preserving quality. Any advice is greatly appreciated. Thanks!
