TiVo and clear qam

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?
