Series 4 Premiere

There are 4 models of the TiVo Premiere, The Premiere, The Premiere XL, The Premiere 4, The Premiere 4XL (Later on called the elite) The Base Premiere and XL are 2 tuner models and both have 2 tuners and are NOT compatible with minis and are compatible with both cable and antenna, The Premiere 4 and Premiere 4XL/ELITE are 4 Tuner models and are compatible with minis but only compatible with digital cable and NOT OTA. There is also the Premiere Q which was only given out by cable companies like suddenlink, which seems to be identical to a premiere 4 or elite but with custom software that stopped getting updated around 20.6 or early 20.7 as these tivos get service via the cable company and not tivo, and therefor the tivo Premiere Q has modifications and differences than a normal Premiere 4 or ELITE but is mostly the same.
