I know it has been posted before but I can't seem to find it with a search but can anyone tell me how to change between the regular and alternate audio tracks hidden on DVD-A's. I've done it before but can't remember the buttons and sequence needed to switch between the regular audio and the hidden alternate audio tracks on the DVD-A discs. Thanks in advance.
