Is there any way to take recorded programs from my 508 hard drive and transfer them to my computer (MAC)? DISH tech support says that the only way is to connect a VCR to the 508 and record the programs to a VCR tape. Since the 508's PVR records programs in MPEG2 I would like to import them into my MAC as MPEG2 INSTEAD of importing them as an analog signal and recompressing them a second time (and further degrading quality)
