I've had good luck shrinking partitions with gparted.  I used the live
CD to do a fairly complex repartitioning of my laptop and lost no
data.  If your partitions are already separate, you should be able to
shrink them and move them to the new, smaller drive, without too much
trouble (make backups!).  Then you can expand the /myth/tv partition.
