I have noticed that a lot of UDF formated CD ROMS can't be read by any of the OS X 10.2 and 10.3 Macs in my company. Any hunches on why? I thought UDF meant "Universal Disk Format". Some UDF CDs cause my Macs to flat-out hang, and require a hard reset. I assume this might be caused by a limitation in OS X of not being up to date with the most recent UDF specs? Can you confirm?
