Am a HTF newbie and just hooked up new system. Can't get the VCR to record or play back thru the receiver. Everything else works fine. Components of system are: Harmon Kardon 525 receiver , Dish DSS, Toshiba VCR, Panasonic DVD, Sony TV. DSS receiver is connected to HK 525 with both S video and composite cables for video and analog cables for audio. VCR is connected to HK525 with composite cables: video play/out from VCR to VID1 in on HK525; video in from VCR to VID1 out on HK525. (VCR doesn't have S video or component terminals.) DVD component cables are connected directly to Sony TV; Toslink audio cable is run thru HK 525. Also, I left in place the original coax cable connection from the DSS to the VCR, and from the VCR to the TV. Should I disconnect it? Any help would be greatly appreciated.
