Corrupted database?  I recommend running optimize_mythdb.pl (and setting 
it to run in a daily cron job) and then running "mythcommflag --rebuild" 
on one of the affected recordings. If that clears up the skipping 
issues, repeat the mythcommflag on any other recordings as required.  
(Don't know how it will affect FFWD/REW, but if it fixes skipping, it 
needs to be done.)
