Write Quality Tests MKM 001
Dual layer media follows the same rules as single layer, but there are certain points on the disc where errors are known to occur the most. We have noticed that the part of the disc where the transition from layer to layer happens is where the PO errors have shown up. Our results are as follows:
We didn't have much luck getting dual layer media both to burn on all drives, since the Sony DRU-710A and MSI DR16-B had trouble writing a successful dual layer disc, and if there was success, to be recognized on the Plextor drive. The DVR-108D and DW1620 came out clean with 0 PO errors each with NEC following with 3 PO errors. The SOHW-1633S was another drive we had luck with, but a successful write was the end of it. PO errors on the dual layer media from that drive hit 192 and were all located between the 2GB and 4GB mark where there were also a few million PI errors!
The DVR-108D performed exceptionally well producing on 546 PI errors on the MKM 001 media. NEC followed with 261224 PI errors which held it and the Pioneer unit at the top two spots.
The Q-Tools screenshot of LiteOn's burn shows the majority PI errors between the 2GB and 4GB range.
It's too bad that there were only 4 drives on which we could test write qualities. Hopefully, future firmware releases will fix compatibility issues on the drives that we have tested in order for media to be recognized correctly on a wider range of hardware.

For future reference if you are going to bother taking pictures of the drives take a picture of somthing useful, the drive bezel. nobody cares what the circut board PCB looks like.xsilver - Monday, November 1, 2004 - link
Also is there somewhere where I can find tests on reading regular dvd-9 movies? my liton 16x reader goes completely ape when there is any scratches on the disc, the 106d is much slower but plugs through.This is when using dvd decrypter
and who the hell uses cd's anymore? dvd's are so much cheaper per m/b to store data.... if someone doesn't have at least a dvd reader, I say quit trying to buy that l33t AMD64 / 6800 and get something useful!

The bitsetting feature on this model is very limited with the current firmware in that only DVD+R DL media will be autoset to the DVD-ROM booktype.KristopherKubicki - Monday, November 1, 2004 - link
>Also the 108d is the same price as the 3500a where I am.... would it be recommended then?I would still recommend the NEC-3500A. The faster CD writing is worth it.

Can the bitsetting option on the pioneer 108d be explained more? what will it auto set to?I have a 106d I want to upgrade and have found the pioneer to be much better than something like a liteon....
Also the 108d is the same price as the 3500a where I am.... would it be recommended then?
