I have an Expressvu satellite system and am concerned about recording a show a few hours in advance onto a dvd disk. Since Expressvu goes up to like channel 800 is the dmr-50 able to pick a channel that high and record it? For instance if i program it to record channel 411 at 4pm early in the day before work, will it do it? I read somewhere that this player doesen't work well with satellite. Any help would greatly be appreciated. Thanks in advance.
