I bought a 50 pack of Ritek R03 DVD+R which were burning fine at 8X with revision 0256.
Well I saw the media compatability list at BTC.com increased with revision 0557, so I updated my firmware to it.
Now I can only burn my R03 discs at 4X! I used to be able to burn them at 1x,2x,4x,6x,8x.
Now it shows 2x, and 4x.
Ive gone back to firmeare 0256, but that didnt help.
