Comment (by mpc_mythtv@…):

 I should have said - differences between recordings from the same channel
 that work and that don't work appear to be down to mplayer detecting the
 broadcast stream as MPEG-PS or as TS.

 A recording that works with -frames 1:

 Hope that helps a little more.  It looks like a flaw in mplayer rather
 than a bug in nuvexport/myth's perl libraries.
