I've got a bunch of recordings without thumbnails.  I don't think I
can skip through them properly when playing them either.  My backend
doesn't crash, however mythweb does take a long time to load the
'recorded programmes' page.  I believe the problem was caused by
running mythtv with a corrupted/crashed? mysql database after a power
cut.  It took me a week or so to figure out something wasn't right. 
After I ran mysqlcheck, all new recordings were fine again.  Other
than deleting the recordings affected, I don't know how to fix this
but would be interested to learn of a way to regenerate the missing
database data.  Perhaps someone else knows how to do this?  Also, am I
right in thinking mysql has a mode of operation that is more resilient
to power failure?

Kind Regards,
