OK, first problem.   You are missing a command line argument.

What kind of MPEG file is this?  The last GOP index is taken from the database
and it seems nuvexport can't get the number.  This is likely due to it being
a different format than expected.

This is tcprobe not liking your file or the offset being 0ms.

This is due to the first problem.

And that is avidemux2 crashing.

Good, lve MUST be compiled with large file support.  But that's not the issue.

It has implications alright.  What does the recordedmarkup table have for a
typical recording?  I believe I trigger on the highest numbered type 6 entry.
If the HDTV recordings work differently (and likely do) then MPEG2 cutting 
won't work without some work.  As I don't have a HDTV card, I can't possibly 
fix it without your help :)
