I have the same problem. I bought a Mac a few months ago with Lion. And I bought Toast 11. I can't get the videos on the Mac to transfer to the Tivo. Even the videos from my old PC that worked before, and are now on the Mac, no transfer. This needs a fix. If Roxio does not intend to support 'Mac 2 Tivo', they should say so and remove it and stop advertising it. Probably a bad business move these days with Apple selling so well.
