Just out of curiosity, no badness meant.
I used to come here many many times per day after i got a 108 when it was new out, i have now lost interest since 109 is out and its lack of goodness so far.
Anyone else feel the same and is the 109 to blame.
In all honesty:
I'm not having any issues with my Pioneer 109, it works just fine with Nero 6606 and DVDDecryptor.
The burn quality in some cases is better than the Pioneer 108, and in other cases is not quite as good as the Pioneer 108, but I wouldn't call any of the burns poor quality (provided you use reasonable media)
The 109 drive will get better with successive firmwares, and when the better 16X media becomes freely available (ie TTH02, TDK003, MXLRG04, YUDEN000T03 and TYG03)
Of course, this all takes time, so I advise you to be a little patient.
I stuck my DVR-A08XL back into my PC and put the DVR-A09XL into an external combo USB/Firewire enclosure. The 108 is a better drive (at this point). I am also hoping new firmware fixes everything. Still disappointed it does Z-CLV with anything but "real" 16X media and some burn at only 12X(!) Ugh.
