I have purchased a Samsung DVD Recorder (R-135) and I would like to record not only live shows but shows recorded on my DVR. The DVD recorder is hooked up through my Surround Sound Receiver, which is in the rear of the room. The DVD recorder can play dvd's but when I record something it aways plays back blank. Do I have to hook the DVD recorder to my HR-20 receiver itself, or do I just hook it to my a/v receiver? Another issue is programming my channels into my DVD recorder. It is limited to 125 channels, in which I did program. But when I flip through them they all are the same channel. Since this recorder is not a Blu ray or HD DVD, can I record 720 or 1080i to my basic dvd's? The box said HDTV compliant so I figured it was. Any feedback would be appreciated. Thanks.
