i just switched from digital cable to dish--my main tv has the box and the rf output is ch3--my remote tv runs off the same box and the rf output is ch60--the problem is on the remote tv my dvd/r will not reconize a uhf signal--ch14-69. so it won't even let me into the menu to try to set the tuner---the recorder is a jvc dr-mv1s--anyone else have this prob?? p.s.--it was working fine off the digital cable box---
