I have 4 formats of recording units, a vcr, a vcr/ dvd recorder, a dvd recorder and a dvd recorder that records to hdd. All have conventional composite inputs and outputs. All can record to various dvd media. What would I need in cables/software in order to SEND desktop A/V TO any of these units? I know recording would be done in real time. I am not concerned about copy protections as my media player removes them, or at least I think so, as the player can play ANY commercial dvd I have tried. I also use a screen recorder than burn to dvd from the EXPLORER WINDOW. I can record any file saved in this window to the in built writer. In this way I can make 2 copies at the same time, either 2 dvds or 1 dvd and one VHS. There are available usb ports. NO conventional composite video port. I know of no desktop that provides one. I am also using a PC to TV converter to to send COMPOSITE video to my TV. I send audio FROM the audio line out. Can I tap into those connections to send A/V to record on one of these units? I do NOT wish to add an internal card as I do not know what slots are provided and what drivers/ software would be needed. I want to keep this simple.
