You can delete the transcoded recording, then use 
myth.rebuilddatabase.pl to insert the original recording.  If you name 
the show appropriately (i.e. what the transcoded recording was 
called--including the .nuv extension--assuming you don't rename 
recordings with mythrename.pl), it will find the title, subtitle, 
description from the database and the channel and starttime from the 
filename.

Always good to backup before making these changes.

You rebuild the seek information (index) with "mythcommflag --rebuild -f 
/path/to/recording".  After that, you can do commercial flagging with 
"mythcommflag -f /path/to/recording"
