In my ATV experience with ISO files, it seemed like it was hit and miss for playback over the network. Some files play extremely well with no issue. Then another, ripped on the same drive, same settings, etc. would just be all choppy. Then of course, I ran into space concerns(vast collection). So, I opted for the H.264 mp4 standard. This allowed for much more consistent results in playback as well as allowing for use with every device I own (computers/portables/etc.). The newest version of Handbrake, released last Nov., allows for the integration of the 6-channel AC3 audio track as well as the old stereo track that was the de facto standard for H.246 mp4 files in the past. Files end up about 700MB-2GB in size and playback is a dream.
