How do you rip a VCD on a Mac? What's the most popular way of ripping a VCD to an .m4v file? I also need to pick a particular audio track (Chinese vs. English).
Handbrake is a nice program that you can use to convert videos and DVDs. Since VCDs are nothing more than mpeg files (with .dat) extension, you can easily use Handbrake to transcode them to m4v.

Handbrake also allows you to select which tracks you want to keep, although if each track is its own file, you may need to use MP4Box to merge them together.

Handbrake is available at http://handbrake.fr, and MP4Box can be downloaded from http://gpac.wp.mines-telecom.fr/downloads/.
