I'm new to this site, and I'm probably not posting in the right forum, but oh well. I've got a 1996 Powermac with an RCA input. It has built in software with mac os 8.5 My problem is that I'd like to record TV on this computer, like a DVR. I need to know how to get cable TV into an RCA form to put into the computer. My TV I have is an old 13" JVC with no outputs. Will an RF modulator work, or do I need a VCR, or something else. PLEASE HELP ME!
