I've noticed that my computer has trouble running high-def movies, and I was wondering what I needed to upgrade to get a smoother preformance. Basically, the audio runs perfectly fine, but the video is a bit choppy, and it lags behind the audio. Now I know that the easiest way to ease this problem is run videos at a lower resolution, but some videos I get are high def from the start, so if there's a way to tell my computer to run the video at a lower quality so that the audio and video sync up, please tell, otherwise, what do I need to upgrade?

For HD content, your CPU is the most critical component for smooth playback. A dual core or quad core would be ideally suited for HD content.

What CPU are you using and at what speed?

It depends what video card you have. The mid level cards like the 8600 and 2600 actually have more video processsing power and can play HD content with a single core CPU. However a dual core is recommended with 8800s and 2900s. They made them this way so families building or buying an HTPC rig wouldn't have to spend big bucks just for home theater use. They also reasoned that most building elite systems with high end video cards would probably want at least a dual core CPU anyway.

How about the Geforce 7, and later 6 series cards? They are also supposed to support hardware decoding.

Here's some more factoids on the subject. The following excerpt is taken from this webpage: [COLOR=blue]http://www.hardwarezone.com/articles/print.php?cid=6&id=2108[/COLOR] Note however that the CPU recommendations listed are in cases where the CPU itself is the processing power. You really can run HD video with a single core CPU if you have an 8600 or 2900, they have a lot of raw HD processing power built in. I would say to be on the safe side though to use a dual core of at least the Core 2 Duo level if using a 7000 series card merely for the fact that Nvidia didn't start talking about single core HD capability until they produced the 8600 line. "...NVIDIA's PureVideo technology is split into two versions. The original PureVideo is available from all GeForce 6 series and above GPUs, and already capable of H.264, WMV, and MPEG-2 hardware acceleration. The newer PureVideo HD standard is a superset extension to the existing PureVideo standard and designed for Blu-ray and HD DVD playback. PureVideo HD is only available on GeForce 7 series and above graphics cards. With both ATI and NVIDIA, enabling AVIVO or PureVideo HD is required through latest set of GPU drivers. NVIDIA specifically used to bundle their PureVideo decoder as a separate software purchase, but is now bundled with the latest ForceWare drivers."
