After latest update of mplayer-plugin some months ago I lost the ability to play mpg files when they are passed through a link (that is the URL ends with that file). It just displays an empty white page. I noticed that I have lost the ability to play other types of online media too.
I didn't gave much attention until today that I wanted to hear online radio. After some experimenting I found out that when I close firefox and install the mplayer-plugin package everything works fine. When I close and open again firefox the problem comes back.
This is what I see when I type about:plugins now hat I have the problem.

I had a similar issue somewhat... the plugin didnt work at all in FF after a while.
Removing the ~/.mplayer directory fixed it for me.

I have had the exact same problem. I saved a version of pluginreg.dat (located in ~/.mozilla/firefox) when the plugin was working (immediately after a reinstall). The next time the plugin went bad, I copied my saved pluginreg.dat over the current file. This restored the mplayer-plugin functionality. The next time it goes bad, I will compare the old & new versions of my pluginreg.dat and post what I find.
