I am currently using Manufacturer ID: RITEKG05 4x, 6x and 8x I have no problems with these if I burn with the Liteon sohw-832s. These disks are also ok when burned with the Liteon lh-20a1p but only on my sunvision divx player which is a mystery. I have conducted a few tests. I have burned to CD-r a few xvid files. The unit sees them as SVCD and obviously wont play them. If I convert the xvid files to divx 4.12 then they are recongnised on CD. Likewise the usb stick will also play the divx 4.12 but this is very time consuming and they also suffer a loss in quality. This leads me to believe that the firmware needs updating but having said that, the xvid files play fine if burned with the sohw-832s.
