I seem to have some serious problems when using 16x omnipatched firmware to rip Video DVD-ROM.
First of all I wonder that the stock firmware only read them at 8x, since the specs at the Liteon site claim that this is 16x reader. We're talking about ROM here, not +/-R. Is this because it's a double layer DVD-ROM perhaps?
Then I tried to read this disc (Rush Hour 2) in Nero CD-DVD-Speed to check the transfer rates after I noticed that another Video DVD-ROM (Amelie) had serious problems around the layer changing point, the drive had to decrease the speed and went some up and down until it became quicker again.
Now as you can see the Rush Hour disc reads perfect at 12x but even stops reading with a serious error message at 16x around the layer changing position. Looking at a quality check of the disc at 16x shows that PI shots rocket high at this point (only at 16x). :a
Codeking published a perfect 16x scan in another threat, so I wonder how results can be so different. Especially given the facts that my drive can perfectly read a crappy NoName (Media ID 0001) DVD+R at 16x, which my old 1653 (who burned it) couldn't even read at 12x!?
By the way, there is no obvious bad damage on the disc, just some very slight scratches.
