I have the 420 which is proving to be an excellent machine for archiving and editing of Satellite and terestial recordings. I do have a small niggle and wonder if it is just my setup or their is an inherent bug in the unit. I have an Echostar Sat system which has RGB output which I connect to the 420 RGB input. With the unit switched off it passes the sat signal through to the TV in RGB mode for an excellent picture. When I turn the 420 on and select Satellite it only outputs Comp.Video on the TV, switch the 420 off and it passes through RGB again. If I record on the 420 it does infact record at RGB quality. Is this a problem with all recorders or is it specific to these Pioneers.
