CD multiplayers have been around for years especially in cars.
It's nothing fancy just a method of transporting a disc from a storage unit in to the player.
Pretty sure there'll be something available for DVDs that's not too expensive.
yeah my stereo had a multi disc player had it over 15 years too
but first time i seen anything like this for dvd espically with so many discs
would save me so much hassle if i could find one, pretty hard to find good storeage space at the right hieght for me
