Advertisements Up until yesterday, we had a tivo series 2 split with a Comcast (standard definition) cable box, all connected to an old standard-def tv. The TV died and we just got a new HDTV and I was trying to figure out how to use a Tivo Premiere (so I can see and record HD video) and Comcast Xfinity On Demand. I was wondering if this could work: Can I purchase a Tivo Premiere and contact Comcast about getting one of their M-Cards for the Tivo.. and attach it to the HDTV in the straight forward way. BUT, could I keep the standard def box and use the other split cable to connect it to another TV input? I know the On Demand wouldn't be in high def, but that's not a big deal. I was just wondering if you thought this configuration would be possible. Thanks for your time!
