RCA DRC8005N Recording Problem

[qanda]This thread is about the Panasonic DVD-REC DMR-E500. Click here to see full specs[/qanda]I have own this RCA DRC8005N Dvd recorder for more than 3 years… It did record to DVD+R and DVD+RW.
I used DVD discs from HP. dvd+r 8x. Once I ran out of them I got other Brands such as SonY dvd +r 1x-16x and Memorex dvd+r 16x … but when I try to record I get message that cannot record possibly disk is dirty?? I cleaned the drive and still get same message… Wont record…
The dvd player works fine but it wont record…
Could this be due to the type of DVD discs I am using…?? Some how I cant find the HP dvd+r 8x anymore… I have wasted plenty money buying different brands of DVD and keep getting same message…
I am getting ready to discard this unit and buy a new one. But I think I will stay away from RCA…
Can you help…???

Try cleaning the lens ans spindle first.
