Too Fast? Too Slow?

I decided to compare the picture quality and performance of MPlayer against VideoLAN. The results are a little interesting. For starters, MPlayer advanced the film slower than my computer clock. But VLC advanced it faster. Playback side-by-side made this very obvious as the skew grew larger and larger and VLC played back the film faster. Color saturation was higher in VLC, and detail and smoothness was better in MPlayer both with and without post-processing on. Unfortunately, slight tearing is visible in both applications.

With both applications running, MPlayer was getting about 70% of the CPU, and VLC about 20%. Once VLC was stopped, MPlayer took the remaining CPU. VLC would peak at about 30% of the CPU. This is a significant difference in processing time. My PowerMac G5 is a dual 2.0GHz with 2GB of RAM.
