Hello. I have the Insignia IS-TV040918 (13") TV/DVD combo and was successful programming my RCA (RCA4258) Universal Remote Control (URC). I used the auto code search and entry mode. Code retreival revealed my code to be 1220. All fine and good. I want to know; should I then program the dvd portion. I can get to the DVD mode by pressing the input button, but the DVD controls do not work. Any suggestions how to get the dvd controls to work?
