After burning 3 DVD's, and reading them back to compute

all three of them generated these error messages during readback,
and all 3 messages show the error was past the 4gb offset.
Is this a media issue or is it the burner?
1- burn dvd at 2 speeds lower than what you used and had failure.
if ok, problem is either burner or blanks.
2- burn dvd at failure speed on a different burner.
if ok, get a new burner. if failure, may be blanks.
3- try different program or burn from command line.
A side question: why does the block io layer assume that all media
have 512 byte sectors?
i believe that is a carry over from disk formatting started by the
IBM PC. [do not hold me to that]
