Jerry,

They don't have to use a "Faroudja type filter", they use Faroudja products for deinterlacing and scaling so they can actually use a Faroudja filter.

The trade off, is that you sacrifice resolution which equates to sharpness.

Stacey can chime in and fix this if I botch it, but I believe Faroudja's LPF cuts out half of the chroma resolution.

Cheers,
