Personally I hate DVD/CD changers. Every one I owned or used generally made me mad. The biggest gripe I have with them is the slow startup time.
Typical moment,
I want to play a CD. I hit the power button.
The changer boots up and starts going through every position to determine if a disc is present.
If it finds a disk then it has to figure out what type of disc it is.
Meanwhile I am about ready to throw the thing out the window because I want to play the disc in my hand, but it will not open to player until it is finished...
If all the slots wer full it could take three minutes or more for it to finially decide it was ok for me to open the drawer and change a disk.
My wife and I both agreed never ever purchase another DVD/CD changer. We bought a nice Samsung upconverting single disk player. I can hit the power, open the drawer, insert a disk and be playing in less than a minute.
