Though if you look at the ATI/AMD Xilleon processor--a chip designed
specifically for digital TV--it appears in what percentage of HDTV sets
today? Back in 2004, they had 85% market share for demodulators and 40%
for MPEG decoders (a.k.a. the Xilleon) in ATSC sets. AIUI, that 40% has
been increasing rapidly since 2004. I'd guess that's a pretty good
chunk of change. (True, ST Micro leads in the European Market, but the
US market is still rather large.)
AMD has announced that their next-generation AVIVO product, the Unified
Video Decoder (UVD), was based on the Xilleon processor with hardware
H.264 and VC-1 (i.e. ideal for Blu-Ray and HD-DVD). AMD also has an
agreement with DivX, Inc. allowing it to implement hardware DivX decoding.
Remember that we--Myth users with "normal" PC's doing our TV--are the
minority. Most everyone else out there enjoying digital TV (whether
using the FCC-mandated built-in tuner/decoder in their HDTV sets or
using an STB) has a graphics solution that was optimized for TV video.
However, as you implied, packaging a TV-specific solution for use in
"normal" PC's probably isn't a good business decision--especially when
you consider the cost of "generic" (versus
embedded/application-specific) drivers, customer support, ... And,
IMHO, a PC user is /much/ better off with a general-purpose graphics
solution. That is, after all, exactly why my PVR-350 is sitting on a
shelf (and was used for almost 4 years as an encoder only--without even
loading the TV out driver).

Though once the open-source AMD/ATI drivers are up to speed
post-spec-release, I will run out and replace all my NVIDIA (with
proprietary drivers) cards with ATI cards.

Definitely true.

Exactly. And, it should prove at least somewhat beneficial for the
vendor (ref my above statement).
