So you've fixed the source of the problem, now fix the problems that 
occurred when you had corrupted tables...  You need to run mythcommflag 
to rebuild seektables and to re-flag commercials.  While your database 
tables were corrupted, any data Myth wrote to those tables while 
recording was most likely corrupted, so you need to recreate it.

For the simple (but long) way, you can run "mythcommflag -all" (it may 
take several days--while max'ing out your CPU--to finish).  For a more 
"surgical" fix, only flag the broken recordings.  See "mythcommflag 
--help" for info.
