joeltobin,
The channel setup instructions are found on page 39 of the manual.
But since you took the time to ask, I'll be happy to help out here:
On your remote:
Menu > Channel > Auto Program
I hope that helps, and let me know if I can help with anything else.

Hi, I just recently purchased this samsung 50" plasma tv. Being very eager to see the HD content on the display, I skipped the channel set up at the intial start up of the tv. I haven't found a way to get back to this start-up process, and now have no access to the channel options in the menu. How do you set up the channels, and plug and play feature, after this set has already been functioning? Thank you
