Or at least I would assume it to be the codecs:

Roommate is complaining of choppy video with hulu so I tried to find codecs for linux but am comming up with nothing but exe's.

Any ideas?

It'a fedora 11.

You should use Fedoras package manager to install software.There wont be any exes in there.

hulu uses flash, if its choppy chances are its a video issues, or not enough ram/cpu to run it properly.

also in fedora if you have compiz-fusion installed and on TURN IT OFF
also WHAT media player is your default ????
it might be a issue with totem,xine,gstreammer mplayer ( the SMplayer front end ) ???? the flash plugin for firefox ?

have you used these help pages ?

There shouldn't be any video or cpu/ram issues seeing as I used to mix music with this thing back when I was running xp.

The package manager didn't have any relevant codec packages.

What exactly does Compiz-Fusion do and why am I better for not using it? The wiki didn't tell me much.

I'm not sure which media player is my default as I have not used one yet and therefore I believe that information to be a bit irrelevant in this case.

I am searching those links you gave me.

Thanks for the help so far and I hope I can figure this thing out.

Any more ideas?

Compiz does all of those little desktop effects you may have seen on the web. Like the desktop that looks like a cube rotating around, or how windows wiggle a bit when you drag them across the screen, or how things look like they are being sucked into the panel when you minimize them. To be honest it is a bunch of graphical fluff that creates an overhead that a lot of things do not play well with.

Flash is one of those things that does not play well with Compiz. There is a way to fix it by modifying you /etc/X11/xorg.conf, but I have yet to see a straight forward how to guide on it. Personally I disable it on my PC even though I have a video card and a system that could easily support it.
