What brand name is the cd that was recorded? In some unusal situations, some cd-rom's have trouble with unpopular or unfamilair media. Thats why companies have flash updates usually labeled "match more media" so I would check the mfg website.
Thats just an offhand suggestion.
The other would be to reburn it at a lower speed, some drives are more picky than others. There are lots of things you can do to experiment, try the first two I suggested and see what happens, report back, maybe others have the same problem.
A Simple search in google showed me a link to here where others share your problem, and just as well, they have a link to dell posting an update to the firmware.
