RCA VR651HF 4-Head Hi-Fi VCR
But is it Cable Box Compatible
All of your reviews that I have read describe the unit in glowing terms - BUT IS IT CABLE BOX COMPATIBLE &amp; does it have a RELIABLE, EFFECTIVE COMMERCIAL ADVANCE???? - The reviews don't addrees these high end features even though I am almost certain that all the VR-650 series units have these capabilities.
