This issue deserves a little note since it has an unexpected impact that I haven’t seen reported elsewhere, and that I’ve personally experienced: 7.2.2 is incompatible with certain wired ethernet adapters, and therefore, if you have one, you won’t get 7.2.2.
But there’s a glitch. If you got 7.2.2 before TiVo was aware of the issue, then you basically just lose connectivity. In my case, I signed up on the priority list, then I was out of town. So by the time my TiVo started complaining about a lack of guide data, I wasn’t here to do anything about it.
So what did I do? First I tried connecting via phone line, assuming that I would get a slight update that would fix the problem, but that wasn’t the case. So I scrounged up another, compatible adapter (one of the benefits of being in the TiVo world is having tons of extra junk around) and I’m working again.
But then I found that when I wanted to show my vacation photos from my trip, I couldn’t, because TiVo Desktop isn’t compatible with my new Intel-based MacBook Pro. Such is life on the cutting edge of technology . . .
