The backend runs the scheduler, the database, encoding of recording if 
you're using framegrabbers, and any commercial detection, transcoding, 
or other tasks you run through the jobqueue.  All decoding for playback 
is done on the frontend.  A 1.73GHz machine of any type is going to 
struggle with anything HD.
