[mythtv-users] DVD Burning

[Tom Kelly]

I've hacked mpeg2cut (that comes with nuvexport) to work
with avidemux2 2.1.0.  The newest version of avidemux2 uses
a different "workbench" file format, and has some different
command line options.

Below is the section of my mpeg2cut that builds the .cut file
and the calls to avidemux2.  I'm not posting the whole thing
because I've made a bunch of other changes to mpeg2cut that are
probably peculiar to me.  I've commented out (rather than removed)
the original avidemux2 invocations so you can see what the changes are.
