I just wanted to post this as sort of a "success story" to let people know that this is in fact possible. Doing some searching before the PPV, I was worried that this would not be possible. However I called Comcast to place the order for the PPV, and then tuned to channel 504 to watch it at the start time. The PPV was WWE Wrestlemania last night, and I was surprised it worked without a problem... considering the trouble it took getting my TiVO initially activated with Comcasts cable card a few months back. The Channel (504) displayed an Indemand PPV logo for most of the day. Then at 6:30 the preshow started and at 7:00 the event started and I watched the whole thing with no trouble. So just in case anyone out there is searching for info on this like I was, it is possible to order a PPV with a TiVo premiere. You just need to call in and specify that you want the HD version, then just tune to the channel at the start.
