Update:

I am usind dvdauthor and growisofs for backup video dvd and under
FreeBSD 10.3 I have a problem with USB ports (my DVD burner which works
good is external USB). I have installed FreeBSD on iMac and internal
dvd doesn't works anymore.
I tried to make a backup on OSX with dvdauthor and burn with growisofs
and it works without problem. No errors.
On FreeBSD 10.3 is copy to USB stick or from to the disk very slow: 6.6
MB/s but on OSX 27MB/s.

And as I wrote before I didn't have any problems on FreeBSD 10.2 and
earlier versions.

Thank you.
