Jerky video- Is it the video card?

I just purchased a new HP Pavilion a830n ([url]http://www.exactchoice.com/profile_3266.aspx[/url]). The picture quality is just fine when I'm looking at a basically static image, but when I'm watching videos with a lot of movement (for ex, a video of a horse running) the video is very jerky and slow to react to quick changes. Could this because of a cheap video card? Isn't a maximum of 128MB-shared memory enough to have decent video quality? I don't understand why this is happening because my old computer (a Compaq Presario from around 5 years ago that is a lot less powerful) plays videos fine. Thanks for your input.

the comp link you posted gave a integrated memory, which would be more like 32 or 64 mb memory instead of 128, but if you compare this to the 5 year old comp video card/processor, there might not be too much difference.... do you have any games on your comps that you can try to see if the fps is really slow, like it skips alot or something. what are you using to play your movies/video?

Thanks for your response. Well, I just used the default player: Windows Media Player 10. As far as games go, I don't really have any games. I was hoping to use this machine for video conversion, editing, burning, etc., and so perhaps I should just return this one and get a computer more suited to my needs (with a better graphics card).

onboard video uses your main CPU to process the video, and given that a CPU is not designed for graphics processing, it will be slower at doing so than a proper video card, and not have a lot of features requred for video decoding.
when you play video that needs certain codecs, which your hardware doesn't have, it will use software codecs. this slows it down also.
and the fact that onboard video uses up some of your main RAM also, means that your "video card" will be slower not having its own dedicated RAM, and the system will have less of its own

onboard video is only designed for simple tasks such as internet browsing, word processing and the likes.

also, Windows Media Player is a resource hog. Since Microsoft has included the skins, it uses up a lot more CPU time than other non-skinned players.

I would recommend downloading another video player like Divx player which will not take up so much resources
