Here's the problem I'm having with my HD-TiVo when it receives a remote command from any TiVo remote (I have tried many remotes). When I press a command, multiple commands seem to be received (even though I'm sending only one). An example. In "GUIDE" - I arrow down one - and the guide moves down 5 or six. Same thing happens when trying to enter a "search" when scrolling vertical or horizontal. It just "takes off" out of control. Thoughts or suggestions?
