As it turns out, Thomson DDT 761X has tda9887.... Not only that, but my 
FusionHDTV3 Gold-T isn't fried at all -- I was suffering from the same 
problem as Gene, Don and Perry.... I just dont understand why it wouldnt 
work with older kernels or in windows.

Oh well.... I applied the same fix to FusionHDTV3 Gold-T as was applied 
to pc HDTV 3000 ..... Now all is well.  8-)
