If the drive got quite "loud" (not really loud, but revving high), I think the program will have used the BenQs maximum speed for that media. For your media (YUDEN000 T02) in the B7T9 firmware, it is 16x - so if it was burnt with 16x the result is excellent if that media is 8x.
I dont know the program, somewhere in preferences or options or so there should be an entry for the drive speed to use.
If you are interested, look in the table ala42 posted on http://forum.cdfreaks.com/showthread.php?t=121530 and search for your media. You see the supported speeds there. Nero for example always selects highest possible speed the BenQ tells it as a default. I do not really like that behaviour, I would prefer to get the default (i.e. certified) speed as a default and be able to choose a higher one myself, but some ppl say burning at higher speeds does not make their results worse, some say even better, so the BenQ recommendations appear quite reliable.
EDIT: I see you have P9 like me, well cannot tell you - maybe you should search this forum for such a table for P9 - or ask ala42 / post in that media thread.
