So...you want to watch programs remotely? Or check out content on your ATV?
You can view any content within any of your iTunes libraries from other computers on your network by sharing the library...and an iPod Touch or iPhone will provide you with a neat App called Remote that allows much more control over your ATV than the original Apple Remote could including seeing everything in your library and being able to jump to content quickly.
Explain exactly what you want to do? Just view what's onscreen, but not control it? I'm confused as to what is your ultimate goal.
