From http://www.ati.com/products/faqs/xclaim3dvrfaq.html:
"Q14: What type of MPEG acceleration does Xclaim VR and Xclaim 3D
provide?
Xclaim VR and Xclaim 3D accelerate the playback of MPEG movies using the
hardware-assisted software decode strategy. The ATI 3D RAGE PRO or 3D RAGE
II graphics chip that powers Xclaim VR and Xclaim 3D has integrated
Video acceleration and Display functionality. Consequently Xclaim VR and
Xclaim 3D perform the color space conversion, scaling, and display of the
MPEG movie leaving the CPU to perform only the decoding of the movie from
the file to memory.
Note that Xclaim VR and Xclaim 3D do not accelerate the decoding of the
MPEG movie from file to memory. Dedicated MPEG hardware is required to
accelerate the decoding from file."
hum. Ok. So it's a half-way. The hard work is
done by the card and the actual mpeg codec itself
is run by QuickTime, on the CPU.
However, the card will not work for playing DVD's, at
least under OS 10 with the stock 4 meg RAM size.
But it *does*.
In my Smurf (OS X 10.4.3) is an ATI Rage XClaim
VR Pro card, p/n 109-43100-00 AMC Ver 2.0. It
has NO sgram upgrade on it. It plays DVDs just
fine.
One exception: I just got a DVD Recorder on my TV
(Black Friday sales rock!). I stuck a DVD+R from
it into my Smurf and couldn't play it. Couldn't
even mount it. Put it back in the DVDR and
"Finalized" it. Now it plays fine in my Smurf.
