No operating system does everything right out of the box--Not Windows, Not Mac, Not Linux.
i heard a rumour that it does not play DVDs .......
Where did you hear this--from someone that knows about Linux??
Most modern Linux distros will do just about everything--but there may be a bit more tweaking.
What does the Linspire website advertise? Since they are selling a product, you should be able to call them and ask.
All operating systems--Windows, Mac, and Linux--are built up of modules that depend on other modules. So--in a sense--they all have dependency issues. A distribution is a package that is tested to work together. When you add things, you can have issues with ANY OS.
Finally--if you are just starting--I would begin with one of the free distros---then buy Linspire if the value is obvious to you.
