Hey Outlaws!

I've seen mentions of various test/calibration discs in the threads here. I'm still using the ancient Video Essentials disc I bought with my first DVD player and figure it may be time to upgrade.

So, what are the best discs available (especially for audio)? Do they come with complete instructions? I don't really know what features to look for because I don't know what should be calibrated beyond what the Video Essentials disc provides.

Thanks,

Sayer
