The only known/remaining problem in that area for MPlayer is MinGW,
which makes support for 64 bit offsets a pain.
But even a dd from ten years ago would have no problem to copy a file of
any size (even including sizes that do not fit in 64 bits).
Since I doubt that you actually managed to break the kernel so
completely, the most likely explanation is that your hardware is broken
and can't read the second layer of the DVD. Have a look at dmesg if you
see any error.
