Not Recognizing DVD-R

I purchased a 50pk DVD-R for 4.95 at a local computer shop, but they don’t seem to work on my desktop, but work with the laptop. The laptop was bought this year, but the desktop was bought 3 years ago. I’ve upgraded my firmware 1653S CS0T (previously 1633S, but I used 1653S.CS0T.patched-cf-mcled).

I’m just wondering why these discs aren’t being recognized by my desktop. Is it because the DVD-R(s) are crap, or something else? :smiley: Thanks in advanced!

It’s likely both: no firmware support in actual writing strategies and crap media.
