Help using mplex in MMT...

[pmcd]

I am trying to take a mpeg2 files (video+audio) and turn it into a a pseudo-SVCD file (mpeg2 with vcd header). A number of ways work sometimes for me playing on a Panasonic DVD player but there is a way using mplex in MMT that used to work consistently but is now failing. I fisrt split the file into a video file (cd01.m2v) and an audio file (cd01.mpa) with bbdemux. Then I used mplex from the cli and it simply fails. Using TMPGenc works with this file while the VCDGear approach appears to fail (I am not 100% sure as perhaps the CD is the cause though I doubt it). Here is the output:

What is going on ?!!

Make sure the mplex string includes something like "-b 100".
I added this to MMT 0.9.0, as well as an edit window for the string.
May want to play around with this number a bit.

Adding the -b100 option fixed it. Thank's.

Where should you add "-b 100" to the string? I'm getting the same errors as pmcd.

Just download MMT version 0.9.0 from my site:
