I recently purchase this monitor http://www.geeks.com/details.asp?invtid=GL701-TVCT. I haven't installed it yet but it has touchscreen for pc, tv, am/fm tuner already built in. Maybe this will help. As for playing dvd's just install a dvd drive so you can play cd's and dvd's. This hook a xm radio up to the computer.
This may work for you.
