    For simplicity sake, I only did one cut point in the file close to 
the beginning.

In there are the yuv and enc files.  One yuv looks like it has some bad 
blocks in it (the bottom should not be green), one looks good (from 
after the cut).  The mp2f_cut.2 is a -d2 output from the whole 1.5GB 
file, the mp2f_cut.3.cut is the first 2000 lines of -d3.

    Yes, I'm getting QMAT_SHIFT warnings on these.

    I've put the file up too, the first 20MB contains the area I cut in 
this example.  I've also tried cutting in a lot of other places in the 
file just to test, with similar results.  You may want to start this 
downloading while you look at the other file, since this pipe is only 
1/2 a T1.  The end of the file might get messy since I just cut it with 
a dd.
