totem plugin and/or mplayer plugin

[farinet at arcor.de]

I do not remember anymore exactly but if memory not fails the standard
installation of lubuntu comes with firefox and mplayer plugin, correct?

Now, for some reason i installed also totem (and the totem-mozilla
plugin). Both plugins seem to me do pretty much the same, but i'm not
sure which one is better. Or if is sane to keep them both.

Thanks in advance for your patience!
