My first data DVD with 6.30 a coaster

Yep! nero 6.30 hang , no buffer and gave me an error message after seemingly burning 1/3 of a True Image file in the compilation of three images totalling 3.7gib
my burner is a LiteOn It 411S and that was before I upgraded to the latest firmware
Few minutes later I tried to burn the same compilation and it burned correctly
