I've had quite a few problems with the Co-Star remote and it's driving me nuts and I could sure use some help. When the front part of the remote (side with the trackpad) works, then the keys on the back don't work. When the keys on the back work, then the keys on the front won't work. I can't get them to both work and I've yet to get any response from the trackpad. I've tried putting the remote back to IR by Q = spacebar but it doesn't fix my problem. The other problem I'm having is I can't get my Co-Star to work with my DirecTV HR21. I've gone through every single setup option and remote codes and nothing works. I know the remote code for my HR21 is either 00001 or 00003 but when I try to enter these manually, the input only allows 4 digits so I can't do it. This is really frustrating and I'm thinking about taking it back. Any suggestions, tips, etc? Thank you.
