Hi, I have Dish Network PVR which allows me to keep recorded TV shows up to 36 hrs. When I'm out of space I just copy them on VCR and then delete them from PVR. Now I want to substitute VCR by DVD Recorder in the process described above. So, I'm looking for something not very expensive but which would work with Dish Network PVR 500 and would allow me to make my own dvds with lengths up to 6 hrs each. Since I'm new to this could you please recommend a couple of Recorders that I could choose from. Thanks in advance!
