The latest version of LVE has some use too, but I find avidemux2 to be easier 
if I'm just removing commercials.

I'm working on a script to use a program's cutlist info from the MythTV 
database to drive avidemux from the command line to cut out commercials and 
generate a DVD iso. I've gotten distracted though by generating menus and 
shrinking the video using tcrequant.

I have better results adding -V to that to make sure mplex is expecting VBR, 
sometimes I get errors from mples without it.

Perfectly fine method. I personally use the prodvd version of cdrecord. 
Anything that burns the iso to the plastic is fine. :)

I've had some great results with postprocessing using the current version of 
tcrequant (part of transcode) especially with animated content. For example, 
I'm able to fit a dozen episodes of Family Guy on a single DVD with a menu 
with no perceptible image quality loss.
