 Problem #430 is back (I tried to reopen the bug, but I don't have
 permission). When two shows are consecutive in the schedules the latter is
 not being recorded. I have 64-bit OpenSUSE 11.1, myth 0.21-25 (it should
 be svn r20501), 2x DVB-T tuners.

 This is not happening everytime (in about 50%). I thought, that problem
 could be in tuners, so I tried to increase tuning delay in mythtvsetup to
 maximum (2000ms), but nothing changed. I realized, that this occurs no
 matter if the shows are on the same channel or each other on different
 one.

 Actually in my case this error happens even if I have 10 minutes break
 between shows, because I have overrecording enabled.

 And I really don't understand why mythbackend just gives up, because it
 has another tuner available for recording, so why it is not using another
 one, when he believes that the first one is occupied (even it is not
 true).
