I got an Apple TV2 which is brilliant. I have set up Home Sharing on my iTunes which is equally brilliant. I would like to get rid of all my DVDs but I want to rip some of them in a lossless format first; those I can't get in HD/download including about 260 episodes of Frasier. I am using Ubuntu Linux for ripping and encoding using K9copy and Handbrake. I have iTunes on another computer. I have been ripping the DVD's using K9Copy to .ISO and the finished file is the same size as the DVD or the video content that I rip. So I am think I am achieving a lossless .ISO. Experimenting with Handbrake using the Apple TV2 setting is just OK on a 50' Plasma via Home Sharing on the Apple TV2. Dark backgrounds are not as good as the DVD played directly for example. So I encoded some .ISO's using video setting RF:0 on Handbrake which it says is lossless. (RF:20 is the Apple TV2 setting). But the Apple TV2 says "An error occured loading this content, please try again later". The second problem is the RF:0 encoded m4v file is about 4 times bigger than the .ISO. Handbrake says that the finished file will only be bigger than source file if the source file is not lossless. I think my .ISO's are lossless so does anybody know why this happens? Would appreciate any advice or a better method. I want original or better quality and hard drive space is not too expensive anymore. Also my finished files (when played on the computer) have jagged edges around figures which I think is interlacing or telecine effects which I don't know much about. This appears on the Plasma through the Apple TV2 on the Handbrake encoded files. When I play the DVD directly on the TV it is not nearly so bad. Appreciate any advice.
