I want to copy some dvr recordings and some vhs tapes to a dvd burner. Would I be able to use either the "Pinnacle Systems Dazzle DVD Recorder" or the "Pinnacle Systems PCTV HD Stick USB 2.0 TV Tuner with PVR" to accomplish this? What are the pros and cons of either? I really don't need the pvr but the HD tuner would be nice.
