I subscribe to DirecTV and am interested in buying a HD Recorder. Am looking at the Toshiba RD-XS32 and the Panasonic DMR-E85H. 80 or 120 HD is fine but can anyone tell me if these are compatible with DirecTV? I want to be able to record a program from one channel to HD while watching another channel. I have read something re: an infrared Blaster but not sure what this is or if it works with DirecTV. Any thoughts or suggestions would be appreciated.
