a) there are no AIW chips, rather AIW boards have extra parts to
accomodate TV-in/TV-out capabilities. Also, they are sometimes produced
with a slightly lower clock rates or different RAM parts to bring costs
down.

For example: AIW Radeon uses "plain" Radeon chip + Rage Theatre for
TV-in/TV-out + Tuner (FI12xx) + several other chips for sound and IF
stage.

Radeon 64mb DDR has a faster clock and DDR Ram instead of SDRAM on AIW
Radeon. ALso, AFAIK, it is capable of driving two heads.

Generally all (most ?)  chips since mach64 were capable of receiving
TV-in, provided that companion chips (i.e. video decoder) were onboard.
