HK AVR7300 Video Processing Question

[WndrBr3d]

I recently replaced my HK AVR520 with the AVR7300 when I made the move to HD.

The AVR7300 comes with the Faroudja 2300 DCDi Deinterlacing Processor built in, converting -any- standard 480i signal to 480p (using DCDi filters).

My HD Cable box is a Pioneer 3510HD Digital Tuner. It's capable of upsampling standard television from 480i to 1080i.

My question is, which would yield a better picture.

A) Having the cable box output standard 480i channels to the receiver for conversion to 480p by the Faroudja 2300 deinterlacer (while passing through all 1080i images)

-or-

B) Having the cable box upsample all non-1080i signals to 1080i and having it pass through the receiver.

Any help would be greatly appreciated!
