We had to get a new entertainment center and sometimes (a lot) - the TiVos do not receive the commands - usually the dogs is standing in front of one of them. Is there a device we can purchase to help fix this? I looked at a few products but I was not sure which one that TiVo Series 3 and TiVo Series 2 would work well with. We also use Logitech 1100 to communicate to the two TiVos. Thank you!
