Your question is pretty straightforward, but the answer can get complicated.

First, try assigning these devices to the existing DVD, CD, VCR, TV devices already on your Neo. You can do it without having to hook the Neo up to a PC. Read the owner's manual, it'll tell you how. Don't have one? Download it from the files section, or download from pronto.philips.com.

If your specific manufacturers/devices aren't listed, you might find files that other Neo owners have uploaded to this site, containing all your codes. Try finding them in the device configuration files menu, under the files section of this website. Or you can manually add each individual code to each button. Check out the owners manual for instructions.

Or you can create your own custom Neo configuration on your PC and download it to your NEO. I'd start to familiarize yourself w/ this process by reading the help menu of NeoEdit software. You can download it from the files section of this site as well.

If you have specific questions after that, you can search the existing forum here, or post a new, specific question.
