So here's a question to prove just how little I know about what really goes on between the CPU and the screen -- I have video that I've compressed using Handbrake into an .mp4 file that I keep in iTunes as a movie. It was originally NTSC and since I live in the US, I assume that the DVI-out on my MacBook is NTSC-compatible. Question: If I visit relatives in the UK, can I connect the DVI-out to their PAL television to view the video? Follow-up: I compressed the file using "original framerate," i.e., 29.98 fps. Would it help to re-run the compression to generate a 25-fps mp4 file? (I realize that I could probably have done this anyway to save some HD space.) Any help welcome!
