I work for a funeral home and we would like to start creating out own Memorial DVD's. In order to do so we are looking into purchasing a MacPro and using iDVD. In order to play our dvd's here at the funeral home we like to loop them when burned to make it easier for setup. I've heard that with iDVD it can only loop a maximum of 15 minutes. I've also heard that Adobe Encore would fix this problem. Could somebody confirm this for me?
