I'm having a problem trying to get the remote for my new HR20-100 to control my new TV. I just purchased a 32" Dynex (Best Buy store brand) LCD TV, and I don't know which brand to select to find the remote codes. Dynex isn't listed as a choice, and I'm not even sure if all the Dynex's would be the same manufacturer "under the hood" anyway. How do I program the remote to operate the TV? All help is appreciated, thanks!
