I have an ATI REMOTE WONDER II that works great with my computer but i wondered if there was a way that i could have it control my non-computer tv and dvd player as well.

To my knowledge, all of the Remote Wonders (I and II) use only RF to issue commands. Your TV and most/all home theater equipment use IR (infra red), so without some sort of 3rd party device that will convert your RF --> IR, you can't do it. On the other hand, if you get an IR receiver for your PC (just get a Windows Media Center remote from www.newegg.com for like $30-40), you can just use a Logitech Harmony remote to control your TV, Receiver, DVD, PC, and pretty much anything else with an IR receiver (including the XBox 360 when it comes out). I have a Logitech Harmony 880 on the way, and I'm tempted to get an IR --> RF/X10 transmitter so I can control my lights and everything with that same remote. Check out the Harmony Remote board on this site for more information about the remotes.

I just purchased a Harmony 880, and I have a ATI All-InWonder 9600 XT in my home theater PC. Ia am interested in controlling this with the 880. Have you controlled a HTPC with the 880, and if so how did you do it?
