One thing that is different in my setup is that I have a software 
encoder (MPEG4), whereas it sounds like you have a PVR-x50.  In the 
transcoder settings, make sure you choose to transcode to MPEG-2.  If it 
is set to something different (like RTJpeg), it will re-encode 
everything and from what I've heard, RTJpeg is bigger than at least 
MPEG4.  Plus it will take much longer because it is re-encoding, rather 
than just trimming.  I may not totally understand what is going on under 
the covers, but I know it has worked well for me once I set everything
