Does anyone have the following setup working with the 760?

Windows Vista Home Premium
Windows Media Player 11
Tivo Desktop 2.5.1

According to the Tivo site Tivo Desktop Plus is not required.

Tivo desktop is setup to automatically import transferred video files in Window Media Player.
The transferred files play fine on the PC from WMP.
The 760 memory card shows up as a device in WMP.
I can setup the video file to sync to the card.
When I attempt to sync the video file that was loaded into WMP from Tivo desktop to the the memory card on the 760 WMP attempts to start the conversion, but then shows it as conversion failed.

Any pointers would be appreciated.
