I'm in the process of revising Stanton Finley's guide to installing MM Codecs and Java on FC6 as his last ones were for FC5 and since he's moved to Ubuntu it looks like he might not update them himself. Also note that it is only for multimedia and Java as I don't use any proprietary drivers and the only Java apps I have are JAlbum and Strangebrew.
I'm having a few beers and trying to watch some Poirot at the same time so I may have borked up some things. If someone with a clear head can take a look and see if I have I'd appreciate it.
