To make a long story short... I have a new Motorola DCH6200 DVR from Comcast and a Tivo HD without a cablecard. The Motorola box has an M-Card in the back (behind screwed-in enclosure). Can I remove the M-card from the Motorola box and move it to the Tivo? I'm assuming that's the reason that's why cable companies are now required to supply cable cards in their boxes? I'm not going to fry anything? Anyone tried this? Thanks.
