Are these files stored directly on your hard drive, or are they being streamed to the system? What OS are you running and what software are you using to play the files? What are your idle/load CPU temps? Have you installed all the newest drivers for all your hardware?

Are you also trying to do 720 or 1080? Your setup should be ok for 720, but I don't think it will handle 1080.

Just finished up on a similar issue ... turned out to be the GREEN drive was not "good".

... OP ended up using a diff 7200 model ... worked great.

Still .. It is too early in THIS thread to say anything, for certain ... just wanted to make sure the GREEN report got posted here, since one just failed (affecting video) on an adjacent thread.

I am running Windows 7 Ultimate and using XBMC to play the movie files. My drivers are all up to date and I do have the files on the HDD. I haven't been monitoring cpu specs at all but will look into that and post back. Thanks for the quick response.

1080, Where am I lacking? CPU, Memory, HDD?

If it does turn out to be the drive ... these are your best replcement options (will work).

Samsung SpinPoint F3 1TB 7200RPM

.. or ..

Seagate 7200.12 (1TB model)

Both are under $90 ... The Seagate sometimes sells for $75 ... now it is $80.

AGAIN ... I just wanted to get this info posted ... for reference ... if/when needed.

I am 99.999% certain that your config SHOULD support smooth 1080P/30 (at least).

And, by setup ... I am NOT talking about the HDD (though) ...

... I just meant that your IGP and proc look good ...

I would suggest more ram, tho ... make sure you are sharing as much RAM with the IGP as bios will allow ... more ram (2 more GB) would not hurt anything ... might help.

I'm not that familiar with the 4200. You sure it handles 1080 video decode? Even with 2GBs of ram and a slow dual core? I'm also not sure of XBMC. I'm thinking this is the Xbox media player? Are you trying to stream something you downloaded off xbox live to your computer? If so, and if the 4200 can handle 1080 content, I'm thinking the issue with your dual core.
