I have an RCA TV (Dish Network HD34-310) hooked up to an HR21-300 using CPNT1 on the back. When I power the system on using the "on" button on the remote, the TV and DVR turn on as expected, but the TV always come on in antenna mode. If I turn them on separately using the "PWR" button and the slide switch, it will turn on in the mode it was in when it was turned off (CPNT1). Does anybody know of a way to set the "on" button to not change the TV input? I remember seeing a sequence in the manual to disable the TV input button on the remote, but I don't know if it will fix the problem. Any ideas?
