[CentOS] Why shouldn't I expect more of CentOS/Linux?

I do appreciate everyone trying to steer me right so that I can 
understand the deal with Linux and CentOS.

A lot of fair points have been made, and I've got to think about it a 
bit. Some people seem to be saying I can do the things I want to do, it 
just takes some work. Some people say I should lower my expectations of 
Linux. I suppose it's a little of both. Manage my expectations and be 
prepared for things to not be so clear.

We'll see if I can get this dvd-rip software to fly. If so, I may be 
over the worst of my conversion pains.
