Drjohn - I'm afraid, the only solution is to sell your player for parts. The Philips drive mechanism used in TriVista (and also kw SACD) is no longer beeing made, and no longer available.
Krell had run into the same problem with their SACD Standard mk II players, but they were able to develop an 'upgrade' kit, that replaces the Philips transport with their evo series DVD-rom drive. That was certainly time consuming for them, but at least they did not leave their customers with nothing.
From what I read on British forums, MF in the UK was offering a great discounts (up to 50% off) on their current players for TriVista owners that faced a drive failure. You may ask US MF distributor about that too.
