Hi,  I've installed acroding to above link.(my mpalyerplug-in version 0.8.0)
mplayerplug-in is not working with mozilla1.2.1. When I am trying to play an
embedded video from a site, I just see "mplayer plug-in - Loading movie"
with a white blank page, but nothing comes up.

I am running RedHat Linux 9.0 with default kernel
Mozilla version - 1.2.1(default also)
MPlayer version - MPlayer-0.90r5

Please help me with this. Where am I doing wrong? What measures should I
take in order to play quicktime,wmv(asf,asx),rm movies in my mozilla browser?
Am I using the wrong version or is it a bug with mplayerplug-in or
mozilla?

Thanks in adnavce,
