Error Message: "Windows Cannot Read From This Disk."

I recently burned a couple of CDS (filled with videos and mp3s) and MADE SURE that they worked properly and were burned correctly BEFORE I deleted the videos and mp3s from my computer. Well, I burned about 5 cds. I was checking over some of the CDs and 2 of the burned CDs dont want to work. I get the following error:

"Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows"


Why am I gettin this? Im POSITIVE that the disk was burned correctly but now all of a sudden Im gettin this error. I got Windows XP SP2, Gateway Computer.

have you tried the cds on another pc?
in nero you can set it to verify after burning.
try burning slower in the future (and dont do other things on your pc while burning)

also is there any other disks you could try, could be as simple as a cleaning...
