I really don't think that adding Tivo software to a comcast DVR is going to make the comcast DVR that much better. Part of the power of a Tivo is the guide data. If the future comcast box(with tivo) is still using the same comcast guide data, it is still going to suffer from cut off recordings that start/end early or that start/end late. This is going to happen even if the Comcast Tivo has clip protection, because the guide data will still be incorrect. This is the by far the biggest complaint that I have with the current comcast DVR. One thing that the Comcast DVR is very bad at is setting a recording by show title. I find it to be fairly reliable when setting the series by the guide view. On a Tivo, it is dead on either way, lets you know about new and old episodes on different channels, and will switch the series recording if your lineup changes or if the show comes on next season. That being said, I really don't think that slapping a Tivo gui on a comcast box is going to solve the current problems that Comcast DVR users are facing. If Comcast wants me to spend extra money on a Tivo interface on their boxes, they had better give me ALL of the Tivo features or I'm not paying extra money. 1) Better Guide data(the same that tivo uses) 2) Better ability to reliably add shows to record and shows conflicts 3) Better reliability (record the entire show, not just half of it(mtv top 20) 4) Better Accuracy to record the entire show even if it starts a little early or ends a little early. 5) TIVO REMOTE(I'm so sick of accidentally pressing the wrong button the comcast remote and getting stuck in some sort of loop in their system. Their "my DVR" button often doesn't even bring up the DVR option in the menu without switching to a different screen first.
