Just for fun I tried looking at this. 1.6 GB doesn't feel 'small' to
me, but times change.
The cutting is a two-step process: once with no cutlist to remove all
but the main video and audio streams, then a second does the cuts. It
doesn't work well with corrupt recordings and still complains about
corrupt packets at the start of each segment. There's some KFC ad
leakage around frame 39442 :-)

If you want to reset this cutlist, after restoring the .old file
and rebuilding its seektable, you could try:
mythutil --setcutlist
