Hi John,

I occasionally end up with recordings of "blacked out" hockey games, 
where I end up with 3 hours of recording of a still frame.

For some reason mythpreviewgen never seems to complete with these
recordings (it doesn't die, it just never finishes.)  mythtv refuses to
delete them.  I can kill off mythpreviewgen, but the second I go to
select the recording to delete it, myth starts it off again.   It makes
it almost impossible to delete these recordings, and is extremely
frustrating.

I normally end up deleting the recording in the filesystem, killing
mythpreviewgen, restarting mythfrontend, and then remove listing of the
recording.

While it would be nice if myth wouldn't record hours of a still frame,
or for mythpreviewgen to cope with it (choosing a frame to preview
shouldn't be that hard when they're all the same!) ...  it would be nice
if delete just worked.
