I just upgraded to a Genie but I also have two old SD Direct TiVo's and got D* to install a SWM16 so I could keep one of the TiVo's for my son. He is blind but is somehow able to navigate the TiVo GUI via the sounds and has for years.
Been thinking maybe he should upgrade at some point to a THR22, besides it being HD is the GUI pretty much the same?
Main features that are different from old TiVo?
Are there any major bugs besides On Demand doesn't work?
