In re-hooking up this VCR w/ new eqmt. I find that suddenly I get all VHF channels correctly but the UHF channels are in the wrong place. Example: channel 19 is found on VCR channel 70. Channel 48 is found on VCR channel 104 and so on. How can I get this unit to put the right UHF channels in the right place? I've lost or misplaced my manual and can't look there for answers. Thanks, Ed
