I am looking to replace my used PHILIPS DVDR985 with another used unit. Are there any particular brand, model, vintage that will allow recording of COPY PROTECTED discs used in a current player? I can do this using a VGA converter box and my computers dvd rom drive. Is there a box that works in the opposite direction? Meaning I can feed an analog line level signal to it then use my VGA connector on a standard flat panel? For dvd/vcr combo units how do I distingquish a dvd RECORDER versus a PLAYER? Two way dubbing? With and without external patch cord? With and without tv tuner, rf in/outs? Too many variables. Documentation hard to find even on line. Any help welcome.
