Hi everyone. I want to say first that I am thoroughly impressed by the breadth of knowledge by folks on here. Anyways, here is my dilemma. I like my Apple TV, except for the fact I have the 40 GB systems that can't do more than 7-8 movies on it at a time, and its very restrictive in terms of format. Very annoying and drives me nuts that you have to hack it to add another drive to it. I would like to build a file server with music and movies, but I want to put my DVDs into a format that I could use later with other systems that allow streaming (I believe newer TiVos could potentially allow streaming, or even media PCs?) What is a good format to put my movies into so Apple TV can view them, but if I add another streamer to another TV (because I won't get another Apple TV while its so restrictive), if the movies are on an NAS, I can pick them up from any system (Linux or Windows based) and watch them? I am not opposed to hacking my Apple TV since I can't use it as much as I want anyways. Thanks in advance!
