Hi Neil,

exactly for the same purpose I use avidemux:
media-libs/avidemux-core
media-libs/avidemux-plugins
media-video/avidemux

Before doing something serious with it, make a copy
of any video you have and figure out, where the 'A'
and 'B' marks start and end...its annoying to have
one GOP of a commercial left in the middle of an action
scene... ;)

Last thing:
You need to cut this way:

The stream:
Start of the GOP...delta image...delta image...delta image...delta image
Start of the next GOP...delta image...delta image...delta image...delta image

You can put the 'A' mark anyway between the start of the GOP and the
end of the GOP. BUT you need to put the 'B' mark exactly at the start
of the next GOP.
By switching between the 'A' mark and the 'B' mark before cutting, you
can see whether the images will fit together...

Sometime you have to move the 'A' mark a delta image forth or back...

Often a couple of GOPS are repeated after the commercial has ended.

Good luck!
Best regards,
Meino
