I purchased the RC71 off ebay because I really like the smaller style of it. Anyways it arrived today and works fine on my C31 client for guide, channel changing etc. however I have hit a road block. I'm trying to get it to control my tv (Vizio) however going into Settings/Program Remote gives me the code however shows the steps for the old remote (slide the top to TV mode). Can anyone help me out? Ive tried holding select and mute until it blinks twice then entering the 10 codes it suggested one at a time with no luck. Called DTV they werent able to help either.
