my friend has a problem copying files from cdrw cds to his HD. it's usually movies in .dat and .avi format. and it's not only him, i think other coputers have same problem. when the copying almost done when it says that 5 sec left. it gives some error " not valid 32 ... something" tryed in dvd and cdrw drives, same error. but it reads file from it just fine. i have win xp and burn with nero, he has home edition. any ideas how to fix it?
