Use VMWare or VitrualBox it is much better software for VM.
Linux does have Media Players. It is just finding the one that is right for you. I used several and i dont remember the one i liked off hand. If i had names i could tell you. Amorok! thats it.
That was a good player. K3B is a great burning software. There is so much choice when it comes to Linux that is what makes it tough. I mean
DistroWatch is just one of the many places you can go to find information about the various Linux Distros. There was over 800 or something like that different ones last time i looked. You have to find one that is right for you.
Gnome or KDE
Debian, Suse, BSD or other
I mean that is jsut for looks and for kernel aspect. Right there alone you have almost 10 different choices and that is just basic stuff from my limit knowledge of Linux.
First thing you should do is get a few distros and try out the LiveCD's they offer.
Ubuntu for gnome interface
PCLinuxOS for KDE
That way at least you will know which style you want to work with. From there you can find a distro that is more suited to your needs.
Yes there is also way more than just Gnome and KDE for the window manager. Those are jsut the 2 i know of...
