Ok - i just got invited to a beta test for new Tivo software….

Before joining there is a message:

"If you have purchased or personally upgraded a TiVo box with more than the manufactured standard recording capacity, please do not enroll it in this program. Doing so is at your own risk — if there are issues with the hardware and the beta software during the program, we cannot support you. If you are using a TiVo Verified external storage drive, you can proceed in enrolling."

Any thoughts on this? What are they doing to those of us who have upgraded our hard drives?
