i have to output a piece of video for an online London Gallery. They want it in either of the following formats: .mpeg .vob .wmv .m2v. I recently gave them an MPEG-4 and it wouldn't play correctly on the website. Now they tell me they need it in MPEG1 format including sound in MP3 or acc format (in the same file). This makes no sense to me and I don't see that option. Does anyone know how to do this?? I assume it's some sort of PAL-like thing??
