http://www.figureitoutproductions.com In this video I will show you how to get the best image quality out of your Sony Playstation 2. I also talk about a device called "PS2 to HDMI." Music provided by Epidemic Sound.
This video shows how to Output Component video, as well as Digital audio, through an Optical cable on a Playstation 2. This is particularly useful if you're trying to connect a PS2 to an HDTV. Take note that the PS2 does not have in game Dolby Digital, few games actually support it, and when they do it is just for pre-rendered cutscenes. However, optical will also allow you to use Dolby Digital on DVDs, so you can get Digital Stereo or Digital 5.1 out of the PS2 that way.
