ProjectX lets you remux or output as seperate files you have to tell it in the 
process window what you want, either TS or demux. Avidemux can use either, 
under the audio menu is the option to use an external audio file.
 Right now though I've found avidemux to have an odd sync issue that the 
author is beginning to look into, but if u use ProjectX to cut commercials 
you can then use mencoder to do the encoding, at least till avidemux solves 
the issue(which only occurs for the late night talk shows for me...?).

anyway, i'm outta here for the evening...
