some players just can't play certain disks. One of my friends has some pioneer thingamajig and it won't play any Memorex brand CD's. No idea why. Got another brand and it worked. I am guessing all your burned CD's are the same manufacturer, so go buy a CD plack from walmart or something.
Also make sure you finalaize the CD after burn, and not "leave this disk open for multisession" or something similar.
And this forum is for CarPC's. Not HU repair or diagnostics.
