I have found Xine's Mozilla Plugin to be a lot more reliable and easier than mplayers. I have not come across any problems in using it and I feel it does not get a lot of press, because it's in GXine, thus not many people know about it. Xine is a stable and tested backend. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I forgot to add that daily builds of the plugin are available at http://cambuca.ldhs.cetuc.puc-rio.br/xine/ as a source rpm.
I'm not sure what you're asking for here. Could you elaborate? Are you asking for a new ebuild?
