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).

??? Are you serious ? If i want not to miss shows because of errors in mythbackend, it is feature request ? If I want mythbackend not to write "recording failed", it is new feature ?

I have 2 tuners and mythbackend is unable to record latter show even if both tuners are not occupied. This is definetely bug.
