Alright, call me crazy, but I could have sworn Handbrake made .mp4 files. It says "MP4" in the settings, however, the output file is ".m4v". I tried different presets, I tried my own, and everything outputs ".m4v" I resorted to making .Avi, but I figured I should stop and ask you people to see if there is a way to make .mp4. Reasons for choosing mp4 over AVI: -mp4 plays well with Quicktime -I don't notice a difference in size or quality -it also works on the Ps3 AVI Files: -are of decent quality and size -work on the Ps3 -are difficult to edit in Quicktime, when I need/want to. So, any thoughts? did I do something that makes it choose .m4v over Mp4?
