DVDA DVDs have higher CPU usage?

Hello,

I put together a simple looping menu background for a short DVD that I made recently, and while watching (after burning) the menu loop on a 2GHz laptop (using PowerDVD), I've noticed CPU usage oscillating between 20-80%. Actually, if I breath playback will stutter. When I drop in a commercial DVD, my CPU usage is around 50% without even a hint of stutter. Why do you suppose DVDs I make are so CPU hungry? I'm using default settings. Are there better ones? Interestingly, I'm doing everything in 5.1, but dropping to stereo makes it worse. Any thoughts?

Your PC has to decode the MPEG video in real time, so if the video is more complex with motion or detail, then it will need more CPU. Hollywood DVD's are carefully engineered to minimize the decoder overhead. (Using software that we could never afford).
