I prefer to have my music, radio and sat coming through the normal two channels but want my dvd's in 5.1. This is impractical with my current av (Yamaha 750se) as I have to go into the menu and change the speaker set up and turn the sub off everytime. The only solution I can see is to either get another amp with 5.1 sound just for the dvd (yamaha s540). Or get a dvd system and ditch the supplied speakers and my current dvd. Is there any other alternative? If not, all advice on the best way forward would be most welcome as the more I look into what to do the more confused I become.
