I have built a 1-9 DVD replication Tower with the following specs
9 Sony DW-Q28A DVD Writers
1 Sony DVD Player
Wytron 399 Controller Card
I can copy and burn any Type of CDs and any type of VCD movies just fine
The problem I have is burning DVDS.
Basically I can copy any DVD just fine and the duplication unit completes the task just fine without any problems.
When I try to view the copied DVD in most DVD players I get screen freezes and pixelization problems. I can copy and burn this same DVD with my pc which uses a memorex DVDRW without any problems and plays all the way thru just fine.
After doing some looking around I found that thse sony writers were more then likely the liteon 1693S models so I took out one of the Sony writers and flashed it. Now the drive reads as the liteon 1693S model just fine.
I tried copying another disc just using the newly flashed writer and the problem was much better. The screen freezes were not as bad as before I flashed it.
I have tried several different kinds of blank media with the same results. All media burns at 4 X no matter what I set my controller at. I am using DVD -r media.
After discussing this problem with some hardware vendors and other prople it has been suggested that I try burning at a lower speed. But as stated before I am locked at 4X no matter what I set the controller card for in the tower.
Has anyone run into this before?
Is there a fix for this that I have not found?
