I've currently got the 656, but will be trying out the 563 this weekend. I had someone try one of my DVDRs in his 563 and he said it didn't work, but he also said it wouldn't play CDRs so I'm beginning to think he may have a faulty unit. I should know for certain this weekend.
I didn't say for certain the 656 is higher end , I said "I believe" it to be higher end. There's a difference. I won't know until I have the 563 in my hands.
