I have a DVDRHD04. Had so much trouble getting it to defrag.. now.. it will record for the length of time I set it for.. but when I play the program it recorded, it will only let me see about 30 mins of it and then stops. When I look in the browser.. there is the program of the full 4 hours.. No, my hd is not full.. was the only program on it. What can I do to be sure that what I record.. all of it will playback? ugh.
