Fedora 10 was released a few days ago and since Fedora 9 for me was a bit of a dissapointment ,I hoped things would smoothen out in F10 .
The installation was smooth .A nice interface welcomes you at installation . I usually create 3 partitions alloting around 700MB for /boot , 1024MB for swap and remaining (around 40GB) for / .
Fedora 10 got widespread publicity and a number of market reviewers praised it for its server stability , faster boot loading ,etc. New users may be attracted to the distro and might be ready to give it a try without knowing Fedora’s and Red Hat’s aversion to proprietary formats like mp3,avi,flv,etc. That means when one first installs Fedora 10 none of ur mp3,avi,flv files will play.PackageKit will simply ignore these files and not bother to direct you to the suitable codec.
The solution for this is to install the necessary software from dedicated repositories which host these restricted drivers. RPM Fusion hosts a huge repository containing all these packages. To include RPM fusion packages in the software sources do the following.
su
Password: --- Your root password
rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
The rpm will install in a few seconds and will be added to your software source.
Now if the necessary codecs to run a file are not installed PackageKit will direct you to the appropriate source.
I use a Dell Vostro 1310 with a 2.1GHz Pentium core 2 duo processor , NVidia GeForce 8400 graphics card. For graphics on the system I downloaded the necessary drivers from here .
For installing these drivers you have to :
Kill the X server and then run the package.
For killing the X server boot into runlevel 3 .
To do so :
su
Password: -- Your root password
/*Open inittab in your favourite editor*/
emacs -nw /etc/inittab
/*and change the runlevel to 3 */
Reboot your system and as root run the package and your drivers will be installed.
GNOMEs latest version features nautilus with tabs a very handy hack.OpenOffice supports .docx ,etc formats (a huge sigh of relief).
Things I did not like:
KDE appearance sucks. GNOME rocks . However since I am a big fan of VLC and Amarok I was dissapointed with the window appearance for both their GUIs since both are coded in QT .
Mplayer and Rhythmbox might work out as good replacements.
Came across a nice site which serve as personal guides to fedora 9&10 .
Also tried Gnome Do . More on it later

PackageKit doesn’t ignore the codecs. It will not be able to find it however since the repository cannot include such codecs. However once you enable a third party repo like rpmfusion, PackageKit will automatically be able to install the codecs when you play anything that requires it.

Try it out and drop me a mail if you need more details.
I tried the rpmfusion suggestion but now it won’t even recognize the type of stream that it is according to the error even though it said all things have installed fine.
