Does anyone know how to acquire a 6-Tuner M-Card? My cable provider (Cox Cable of Hampton Roads) only has M-Cards that provide 2 tuners. After talking with TIVO support, who determined that my M-Card did not have the proper upgraded firmware. I have been to two of their 'solution' cards and even waited an hour to get to talk to the techie M-Card dude at Cox. They are clueless about any M-Card in excess of 2 tuners (however, they have a new Cox-labeled DVR that does 6 tuners...). So I am looking for another M-Card provider. Can anyone help?
