I have an RCA HiFi VHS and mine automatically finds the soundtrack. My
friend's GE HiFi VHS does the same. You need the manual switch for two
reasons: 1. You can record in one or the other or both. You would record
            in both so that your freinds with stereo but not HiFi can
            borrow your tape.
         2. There's a mix switch on mine that allows you to do both. 
            You have to chose one or the other on playback however.
