i had this same problem when i was new at this. It was because i had not checked the Use Joliet option in Nero when i burned it. Nero truncated some of the longer filenames to having just an FLA extension.

i found out, though, that as long as the disc was not finalized, i could go back, check the joliet option, refresh the disc and all the filenames would be back to what they were supposed to be.
