Hello, thank you for the question.
To answer your first question, there are a number of web technologies that allow you to do remote screen sharing/control. I usually use one called ShowMyPC.com or LogMeIn.com.
As for playing DVD's, the best and easiest (and free) program for this is VLC Media Player. It plays a wide range of video formats, including DVD's.
Great, Ben!! Is that located at vlcmediaplayer.com?
The link for VLC is www.videolan.org/vlc
You should be able to click the links I sent to get to all the software I mentioned.
Let me know if there is anything else you need. Thank you for coming back and trusting us with your questions!
