After numerous conversations and emails I was told the following by Comcast Nashville: 1st card - free - result: charging me 6.95 + 1.50 for the card 2nd card - 6.95 VOD and PPV will work with TiVo HD and M-Card After purchasing the TiVo HD: I returned my digital cable box to the local office and picked up the M-Card. Setup was not so bad but getting Comcast to activate the M-Card was a bit tiresome with all their 'drivers are down' talk. Finally, they get it activated 2.5 hours later. Channel 1 is VOD and it is blank. I call TiVo and they tell me VOD will not work and probably never will. They told me some people run the TiVo on one input and the digital box on another. I stated why would I want to pay for a cable card and a cable box when there is no break in cost from TiVo because VOD doesn't work with their box. Contacted Comcast and working on getting a digital box and returning TiVo. So much for the long awaited move to TiVo - buying a regular DVR recorder now.
