I have a Denon dvd-5000; it won'd read cd-r's

If I just wanted arrognat answers, I wouldn't have posted on audigon. There must be something different about a burned disk, but if you think about it, all disks are copies; so there may be a chracteristic about fatory burned ones that can be reproduced. It's unfortunate that the tone of three of the answers weren't in any way trying to be helpful, but ignorant; at least I was willing to ask the question.

CDR's are different than regular cd's; the substrate is Aluminum on CD's and chemical based in CDR's.

this might be the key; is there a way around this, like recording on a different kind of blank or treating the disks
after they are recorded or? obviously this is not so uncommon for owners of older, worth keeping units. je
