I have my mac mni server attached to tv monitor. every time I turn off tv with remote, the computer shuts down, and when I turn on tv, the computer turns on. The tv is attached via eyetv and hdmi cable. Thanks for the help
It sounds like your mini accepts your tv-remotes on/off signal.
If you don't need to control your mini with a remote, then just turn off the IR receiver (in system preferences, security).
If you do need to control it with a remote, then use an apple remote, and pair it with the mini.
