Encoding Divx from Mpeq for PPC

Hello all,
I tried to convert a Mpeq file (from VCD using VCDgear) with virtualdub. But when I use the parameters from this site (DVD to Divx), it has an error message saying I don't have enough data to continue. Please kindly guide me to instructions on:
(1) How to convert mpeq file to divx
(2) maybe just convert good mpeq file for ppc without going to divx.
My source mainly from DVD, VCD, and recorded TV program in Mpeq-1 format.
Thanks.
