More info on the Sirius S50

Sirius Backstage has some more info on the Sirius S50:

"You can schedule 10 programs up to 4 hours each. All recordings are saved to My Sirius Shows. Just like a Tivo that has been programmed for the future. It will wake up if turned off from the home dock and will record with constant power from the car dock at the time of the scheduled recording. BUT has to be docked with a power source and a good signal to the birds. If you are using the S50 at the time of a scheduled recording, you will be prompted with an option to proceed or not. Same thing if you try to change channels while recording."

4-hours? Interesting. Also apparently some songs can be recorded while others can't.
