Just what processing do you think is going on?  Both MythTV and VDR dump 
digital recordings straight to disk.  Anything more would be foolish.  
The index building is a read-only process that stores its results on the 
database.  It does not affect the recording file in any manner.  This 
index is needed for rapid seeking, what good is it if you don't have it 
prior to playback?
