Hello everyone. I think vizio may have already answered this question (officially) but just wondering if someone has a workaround. Love the costar, love the remote, I thought though since I have a Vizio TV (VF550M) that I'd be able to control everything with My Costar remote. My situation is this: I have basic (non-hd co-ax cable) running to a Tivo. I then have a broadcast hd antenna running to the coax input on my vizio TV. From the costar I can access basic cable through the tivo but cant get the costar remote to change the imput on the vizio tv without grabbing my vizio tv remote. I know my setup is kind of funky (to say the least) but Im cheap and I get what I want with it (cnn,fox news,comedy central in SD) plus the broadcast channels in HD. Yes Im a cheap bastard. Just wondering if theres some way this can be done or do I just have to use the tv remote to change tv inputs. Thanks for your time.
