Stability is in the mind of beholder. Windows can be crashed in a blink of an eye. Mac OS X has been very stable, since the Beta days (I have used all, but 10.4).
If you really need to see those DVD portions, you could run Virtual PC. Most of the good games have been ported to the mac.
MYOB is a very good software for running a business and even comes with a quality manual that is x10 better than Quickbooks.
I'm not talking bookkeeping, I'm talking about running the business. I looked at what was available for Macs, and it truly, truly sucked - amateurish and years behind the Win-platform products, even most of the proprietary-hardware stuff.
Don't bother trying reason with Hank. He's here for just one purpose, to insult Mac owners. Along the way he will try to defend to himself some computer decisions he must be unconciously uncomfortable with.

You'll never get anywhere with him.
Don't bother, is my advice.
When you say "Most of the good games have been ported to the mac," what you are actually saying is that "The games you want to play, but can't, on a Mac really aren't important."
