I would be willing to pass 10 degrees to you.
(If you need more, i could make contact to a user in Mumbai.)

I now got the requested SCSI log.
The drive simply says that there is no "Pre-recorded Information
in Lead-in" available:
READ DISC STRUCTURE
ad 00 00 00 00 00 00 0e 00 04 00 00
From drive: 4b
00 02 00 00
748 us [ 1563073 ]
The answer "00 02" tells that not more than the following
two bytes "00 00" are available.
On my LG GH24NSC0 the dialog between libburn and drive
about media type looks rather like this
READ DISC STRUCTURE
ad 00 00 00 00 00 00 0e 00 04 00 00
From drive: 4b
00 6c 00 00

libburn first asks how many bytes are available and then
asks for the according number of bytes (answer size + 2).
The answer contains at the right location the strings
"52 49 54 45 4b 46 00" = "RITEKF" and "31 00" = "1".
So libburn identifies it as
Media product: RITEKF1 , Ritek Corp
(Involved specs: MMC-5, ECMA-279, ECMA-338)
So in some way, Eike's burner and the medium are at odds.
Suspicious is also the short execution time of 748 microseconds
in contrast to 5000+ microseconds on my drive.
Well, let's see whether the new DVD media yield better
results.
Have a nice day :)
