There are several posts are using TiVo with clear qam channels, but I'm not finding definitive answers and nothing overly recent. My scenario is very basic and straight-forward. It's a university environment using a hybrid satellite/OTA system that ends up presenting the channels as clear qam over in-house coax (no tuner/box needed). I understand that channel guides may be tricky (although our system does have a channel guide), but does TiVo have a dvr that is capable of tuning in/recording our mix of SD/HD (roughly 50 of each) channels? Also, the system uses sub-channels (e.g 2.1, 3.1, 3.2, 4.1, etc). Can Tivo recognize all of the channels?
