XVCD Mux Problem

[SCB]

I encoded an .m1v file with a bit rate of 1500 and separately encoded the audio to .mp2. Tried to mux them and keep getting this error:

What do I need to do to fix this?

Your subject line says XVCD, but the mplex command string shows generic mpeg1 (./mplex -V -f 0). Try changing to "-f 2" for user-rate VCD.
