Phillips 1640P 2.5 - no 2nd layer

I have recently bought this DVD burner and I was anxious to start transfering my CDs to DVD.

My first attempt:

Nero 6.6.0.13
Firmware 2.0
speed 2.4x, 7.98GB of data
medium: TDK DVD+R DL 2.4 speed certified vers 1.0
Result:
1st layer writen, as soon at it goes to 2ns layer it stops recording and Nero produces an error.

Second attempt:
Nero 6.6.0.13
Firmware 2.0
speed (forced) 2.0x, 7.98GB of data
medium: TDK DVD+R DL 2.4 speed certified vers 1.0
Result:
1st layer writen, as soon at it goes to 2ns layer it stops recording and Nero produces an error.

Third attempt:
Nero 6.6.0.13
Firmware 2.5
speed 2.4x, 7.98GB of data
medium: TDK DVD+R DL 2.4 speed certified vers 1.0
Result:
1st layer writen, as soon at it goes to 2ns layer it stops recording and Nero produces an error.

anyone care to speculate what is going wrong?
Thanks for all your input.

P.S. this is part of the log Nero produces:

why do you keep trying this nero version when you can have a free update to nero 6.6.0.18

yep, try at least 6.6.0.16 or 18 if you want to try DL burning
(or try a other burning program, e.g. let nero write your data as an ISO to your harddrive and then use dvddecrypter for burning)

I didnt realize that 0.13 would be problematic, since it has functions for DL burning. I will get 0.18 and try again. Thank you all.

Is this a Ritek disc?

Try latest firmware P3.6 or B3.6 (Bulk).

RitekD01 are known to have trouble with layer change.

Use DVDIdentifier to retreive mediacode.
