[MPlayer-users] How to extract mpeg track from a vcd?

I learned from the document under mplayer's homepage that a program named "readvcd" can extract mpeg data file from a vcd. I try it but met with some problems. The major one is that it will stop if there is a little error on vcd but mplayer can read it from cdrom smoothly. So if a data file is 60m long, for example, there is an error in 30m, then I get a output mpeg file only 30m. It's terrible. Is there any other program can extract date file from vcd? Thanks Dion king
