Horrid Choppy Video Playback

Not sure where to post this, but it's been driving me crazy for over a year now.

I do a lot of video editing, and ever since about a year back, I have NOT been able to playback a DV quality, or even relatively high quality movie smoothly. I have analyzed my CPU usage, and as soon as I play a movie my CPU usage shoots up to 100% and the frame rate dies to about 3 FPS.

I have a DELL Dimension 8300 with 2 GB RAM and a 3.2GHz Pentium 4. I have a ATI RADEON 9800 Series. I'm running dual flat panel monitors. I have Windows XP Pro. I've thoroughly cleaned my startup programs, and get the same 100% usage when I run the video without ANY applications running. I also get the same result in all players, Windows Media, Winamp, etc. It seems to only be with high quality DV video, lower bitrate video plays fine.

To my knowledge, I have the most recent ATI drivers installed. My memory usage is virtually 0% when I run video, but the CPU goes crazy. Can anyone offer some advice? This is a very important issue for me to resolve.

Thanks,
Mike

 

What was the last program you installed before this problem started?
Also did you check for trojans?

 

A conflict between codecs is another possibility to consider.

 

I do not remember what it was that initially caused this. I definitely have no trojans.

The codec conflict has piqued my interest though - when playing WMVs in IE, I get a sort of inverted looking image, which I think is a codec issue. I think the codec conflict could very possibly be something to look at.

How would I go about finding out if I have a conflict, and if so, resolving it?

 

Also, if it helps, I've been having a lot of other trouble with possibly codec related issues, including:

iTunes skipping
the choppy video playback
the inverse video color for WMV files in browser
pops and clicks in recorded audio from my Audigy 2 Platinum

 

Try out gspot, the codec information appliance. I'm certain it will help your cause!

 

OK, I'm going to check out gspot. In case this might help anyone recognize my problem, here are my installed codecs:
