Can Netbook’s play DVDs that were RIPed to a hard drive?

"I have an Acer Aspire One Netbook and it is extermely happy playing DVD and Videos. I have XBMC loaded and use it to watch shows off my media streamer everyday. Depending on the Graphics Card, which is generally the Intel GMA series, you should have no problem running or watching movies on Netbooks, as the Atom Processors are dual core and more then capable of handling the streams.

Media Player works well, although I inherently don't like using it.

I am also running Windows 7 Professional on mine without any hassles whatsoever. You can read about my experience on my blog."

I remember playing DVDs on my old Pentium III at 450 MHz, so an Atom processor should handle that just fine.
