Welcome to SatelliteGuys... Ive done it with a 501, S-video from 501 along outswith Rca Audio to my Panasonic S-video in (with audio also) the panasonic uses dvd-rams which you can edit commercials out with...or dvd r 's
They are a form of re-writeable dvd that is supposed to be re-recordable for thousands of times... the higher cost Panasonic dvd Recorders also come with Hard drives making editing easier...but panasonics only record to dvd-r and rams, there are brands that record to Rw's and the +R formats as well.
