To use SVideo and dolby digital what do I need? Do I use the Advanced AV pack or the High Definition AV pack?? This should be the most common way to hook it up, since most people don't have switchable component in.. they'll leave their DVD hooked up, but they want digital sound.. what is the answer? And the HDTV hookup says it does 480p.. what about 425i??? or whatever the normal NTSC is?? ugh this is **** confusing and there isn't a lot of info.
