Yup, the firmware is -540.
The main Tivo screen now displays "Music, Photos
& More" - that's a change from "Music & Photos," I think.
The top entry on the "Music, Photos & More" screen is the server static IP address that never resolves. The bottom entry is, "Disable Home Network Applications." It toggles between enable/disable based on the next screen, which has some text and a thumbs up or thumbs down sequence.
That screen points to
www.tivo.com/pcprivacy, which has an ominous sentence: "TiVo does not permit home network applications to be discovered on TiVo DVRs unless the subscriber actively enables the discovery feature. For subscriber convenience, TiVo also identifies these unverified applications with a computer icon on the TiVo menu."
Just to make sure, I hooked up my Netgear MP101 on the same cable as the Tivo, and it sprang to life with MC immediately.
Interesting, eh? I experimented a bit more and still can't make MC and the Tivo react to each other at all. The 7.2 rollout is apparently brand new and a fair number of people are venting out loud about problems. I'm not going to install Tivo Desktop software or try to move video around, so this is the only side effect I'll notice . . .
