Yep. Nope. A modulator takes a COMPOSITE NTSC video signal and modulates it with a carrier for a particular TV channel, e.g. channel 3 or 4. The original poster wants to convert an RGB video signal, which requires somethig considerably different than a modulator. What Sereno really wants is a scan converter which turns the RGB signal into a composite NTSC signal which can then be piped driectly into the input on the VCR (no RF modulator is necessary; in fact, the use of a modulator will lessen the picture quality). Sereno, if you give us more specifics as to what type of computer and video display you want to record, I or others might be able to give you more specific pointers to devices which will help you.
