help with demultiplex and multiplex

[SoOpAmUrDa]

I am using TMPGEnc to demulitplex and remulitplex mpegs. I click the simple multiplex and simple demulitplex options. When I mulitplex the two files together after I demulitplex them, it says the mpeg might not play cuz of some kind of packet underflow. So I double click them and the mpeg plays fine. So I go into nero and click on the video cd burning option in the wizard. I drag the new remuxed mpeg and it checks the mpeg. It gives an error saying that its streaming encoding is invalid for a super vcd and that the mpeg file is not suitible for a video cd 2.0 disc. Gives me three options turn off standard compliance and continue, reencode video file, and cancel.

Does anyone know why this is happening?....

I have had the same buffer underflow problems...I think it may possibly be an issue with the new versions of TMPG or maybe its just because I never used to multiplex as many MPG2 files as I do these days.

Either way, I switched to bbMPEG and am very pleased with its performance...I have yet to encounter any problems using bbMPG.
