The Chin-glish here is referring to the HDCP aspect of playback. It means
by using a monitor that supports HDCP on its end, an encrypted link is
used, and consequently full movie resolution is possible. "Supports playback"
is not implying the chipset has some special understanding of movies
or movie playback. You still need application software to do that.
I understand the presence of the HDMI connector is supposed to imply
HDCP support, but I still like to verify that for either end of the
link. HDCP may not be mentioned in monitor advertising (because I tried
looking recently for that kind of info).

"The first integrated VGA MB supports Playback of HD DVD and Blu-ray
Discs with HDCP compliant"
What is kinda funny, is if you go to the Specification page off of the product
page, it says:
"Supports HDMI Technology with HDCP compliant with max. resolution 1920 x 1080p
(It may not display 1080p smoothly when playing HD DVD and Blu-ray Disc
due to current version player limit)
If you go to the ATI chipset pages, they're more hardware oriented.

"Protected content can also be played through on-chip HDCP support..."
Some of the acceleration features are listed here:
http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_14603...764,00.
" Motion Video Acceleration Features
* Enhanced MPEG-2 hardware decode acceleration
* MPEG-4 decode support
* Hardware acceleration for WMV9 playback
* Supports top quality DVD and time-shifted SDTV/HDTV television playback with low CPU usage"
Picture quality on 690G (X1250 core) is compared here.

"For video acceleration features, the X1250 is capable of hardware acceleration
of MPEG2 and WMV playback. MPEG4 playback decode is not hardware accelerated,
but it is supported in software via the driver. DVD and TV (both SD and HD
resolution) playback can be offloaded from the CPU, but we have seen some
severe choppiness or blank screen issues with HD media formats at 1080p -
although 720p worked fine. AMD has indicated that this issue will be addressed
in a future driver and the chipset is fully capable of 1080p output with an
upper end CPU and proper software support."
While this article is for X1250 core on an Intel motherboard, you can see the
processor utilization during playback.
http://www.anandtech.com/mb/showdoc.aspx?i=3072&p=17
"With the release of the Catalyst 7.8 driver, the X1250 graphics core has been
touted as having the capability to playback high definition content in 1080p
with an appropriate CPU and CyberLink's PowerDVD player."
It is the usual "dribbling development" issue. When it comes to video playback
(movies), the software isn't ready for about a year after the hardware has
shipped. It takes that long, before it gets close to the initial design intent.
It takes so long, in fact, that reviews sites seldom follow up to see if
the stuff (finally) works right.
