We have been enjoying our home theater for over a year. But during that time it has only been able to play DVDs. When I first put the equipment together I purchased a (used) Sony 400-disc DVD changer. I found the notion of one-touch play appealing, and through the automation system I was able to achieve that objective with the changer. Sony also sells a 400-disc Blu-Ray changer which it has been prohibitively expensive for quite some time.
