To see if it is the USB drive that is the problem, just try moving one
of the problem files to a storage group that is on a SATA drive.
MythTV checks all storage groups to find the files, so you can move
recording files freely between storage group locations.  Use the I key
twice and scroll down to see the file name for any recording.

USB 2 drives are pretty slow, but should be fast enough to play back
any recording as long as the drive is not busy doing something else at
the same time.
