On the weekend, HDNET movies aired The Blues Brothers in glorious high def and DD 5.1. I've seen this movie a million times on various VHS and DVD releases, but someone treated this restoration as their pet project. The sound is simply amazing on the music numbers. Anyway, I would like to record this to DVD, knowing I may lose a little bit of the video resolution outputting to 480. I'm just wondering if the true Dolby Digital Signal will still be passed through onto the DVD or will I lose some of the audio "pureness" of the signal as well? thanks P.S. I'll buy a round of Orange Whips if someone can help me out.
