Comment (by mpc_mythtv@…):

 Hi all,

 I found another workaround - it looks like increasing the amount of the
 stream that mplayer looks at can also fix the problem of non-detected
 video.

 Swapping the command line for:

 I've checked, and it seems that adding -tsprobe <big number> doesn't hurt
 mplayer's identification of MPEG-PS, so this might be able to be added
 routinely.  I've added it to Recording.pm, and it does fix the hang for
 me.

 50,000,000 seems to reliably hang,
 60,000,000 seems to work for some recordings,
 120,000,000 seems to work reliably for me for a collection of about 100 tv
 recordings.

 Nothing seems to prevent the hang for radio recordings without a video
 stream.  Piping in a 'q' after 15 seconds should cause mplayer to quit
 gracefully but feels somewhat ugly.

 Cheers,

 Mark
