Advertisements I have a strange problem that started yesterday on two identical TiVo/DirecTV setups. These are series 1 TiVos connected to DirecTV D10 receivers via serial cable. Both setups worked flawlessly until yesterday. Now, whenever I try to change channels to anything under 100 (locals) with the TiVo remote, the DirecTV receiver doesn't change channels. Also, if I use the TiVo remote to tune them in where they really are (ie channels 908-928 instead of 4, 7, 9, etc.) they don't work either. If I use the DirecTV remote, they work. If I use the IR blaster instead of the serial connection, they seem to work. Obviously, I'd rather use serial, since it SHOULD be more fool-proof. Has anyone else experienced this strange problem or have a remedy for it? Thanks in advance!
