Ok, I picked up a dvd burner to connect to my dvr to get some programs off it.    
What I found was, no matter how I set up my dvr, I still get the black bars at the top and bottom....and I have a 50 inch widescreen HDTV.  It squashes the image.  I'm rather picky about that, so if anyone has had similar problems, have you fixed them?  I have a samsung 50 inch DLP HDTV with a motorola DVR and a samsung DVD recorder.  Any help is appreciated.
