I'm having issues accessing my DVR menu on a multi-room DVR box (i.e., not the main DVR box). When going into the menu on the costar remote, then DVR tab, the cursor turns into a no-go icon. My work around now is to use the FiOS remote to hit DVR button, which brings up the native FiOS menu. I don't want a fancy GTV menu, just being able to use a single remote would be fine for me. Any suggestions or this a known bug? Also, is it possible to program buttons on the costar for specific functions, like the DVR menu? Edit: chatted with tech support, tried changing codes for the box, which didn't help. I don't think there is a button to link directly to the box's DVR menu. Can someone confirm whether Costar overlays its own interface over the DVR? If so, then I think the issue may be the multi-room issue rather than misprogrammed button issue.
