Hi there,

now is the time to build a new Bluray Burner. I try Ubuntu-server and 
xorriso

The problem that the write speed is decrease is still present. So to see 
the problem you don't need to write data to disk. You can do on one drive:

osirrox -indev /dev/sr0 -check_media data_to="./test/bla"

and on the second drive

eject /dev/sr1 and eject -t /dev/sr1

At this moment I had some time to test solutions.

Winfried.
