CD-Roms/DVD-ROMs not showing DATA CD's recorded with other softwar

Hi, after a recent round of WSUS updates, users are reporting that their

CD/DVD drives won't show the contents of data CD's made with apps like Nero.

If I create a CD using windows drag and drop it can see the files fine on the

burnt CD. If iuse a proper commercial CD, like Office, it can read that too.

Just homemade Data CD's do not display any content and show as being empty,

despite using some of the CD space. I've been through the KB, tried various

ASPI, UDF readers etc but to no avail, changed the DMA settings etc. Anyone

got any ideas as to how I can get back to being able to view previously made

CD-ROMs...

Regards
