64-bit stuff is usually just a different flavour of the 32-bit stuff so most simply have a slightly differently named repository, i.e.; "feisty-AMD64" instead of just "feisty".
Getting flash to work was a minor hassle but there's some guides online that are fairly simple to follow. I think the one I found actually had a script that did it for me :-D
For the eye-candy category you cannot beat compiz-fusion, but be warned that if you get it installed wrong it will be a pain until you've figured it out. It's the de-forking of the Beryl project and is now more up to date than Beryl. Also be aware that you MUST
install the 64bit version. The 32bit one which _EVERY_ guide uses will install and seem to work just fine... for about 5 minutes then crash very badly. Just about the only time I've ever had to force power off when running a Linux distro, at least I know it was my fault! Just remember there are AMD64 repo's out there for it.
YouTube - Compiz FusionFor example that video is almost exactly my desktop :-D
I haven't bothered with DVD playback (
have a 360 connected to the same 24" monitor for that) and just use the distributed players for mp3s when I want them. They've done everything i've wanted thus far.
