You're saying that the sound goes
too fast when using the mPlayer plugin to view a website with MP3s?
Do MP3s on your hard drive play normally in mPlayer? Do the sites play normally using another browser? I have no problems with Firefox, for instance.
I checked the mplayerplug-in site (
http://mplayerplug-in.sourceforge.net/index.html) and didn't see anything related to this problem, but you might want to go to
The plugger testing grounds to begin to check out whether this is a browser issue, a website issue, or a plugin issue.
