It just a simple folder system where you can opt for organizing shows in folders. So if you have a number of episodes of the Simpsons they will all be listed under the Simpsons group.It's nothing special, but they refuse to say whether the Series1 will ever see it.

One of the symptoms of my previously stated paranoia was the sudden channel changing screw ups. It happens all the time now. I've tried the "fort" and various other tricks to improve it, but it still records the wrong channel more often than not. I know my cable provider has the right box, I'd just have to ask for it.

...but that doesn't matter since the only way to get serial control would be to hack my TiVo. It appears the software is in there, they just refuse to "flip the bit" on the Series1. There is a way to do it on the Series1 if you hack it. Dumb...
