Splashtop 2 is great, and free for LAN use (modest cost for internet use). It is like Teamviewer or (not free now) logmein. I use it almost every day when I am away to control my wife's PC. I prefer it over Teamviewer as it is less intrusive and does not leave annoying nag screens.
Even if you find another way of doing what you want, I recommend you try this as you can do almost anything on PC remotely from a phone, tablet or another PC. You can even use it to simply watch what is being played on PC (beats Team viewer hands down here.)
Just search splashtop on web for more details.
