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

I had a DVD5000. It does not read CDR's. CDR's are different than regular cd's; the substrate is Aluminum on CD's and chemical based in CDR's.

I agree it was a great sounding machine when it played. I had it in the shop three times in the first two years for complete laser assembly replacements. When it died for the fourth time it had to go.
