I don't think there is an elegant hardware solution to this problem, 
since you will need the TiVo to re-assert control periodically (when 
you go to the main TiVo menu perhaps?). It's a relatively low-level 
software hack, and I'd guess that the information required to do it 
isn't in the public domain.

FWIW, my TV (a Panny) still allows switching between SCART inputs 
even when select is active (ie. I can change channels with the TIVO 
connected via a SCART if I want to).

Still reckon VIOM "intelligent" control is your best route...
