AnyDVD currently does not work 100% with the Liteon 20A1H drive. This may include some other Liteon models as well.
What will happen is a rip using AnyDVD + any software program will make it to 50% on some dual layer discs, then will return read errors. If a ripping program is used without AnyDVD, there is no problem.
It has been suggested in this thread that this isn't an issue with AnyDVD... it's an issue with Liteon's firmware failing to meet "DVD Firmware standard specification".
Does this make sense? Is there anything Liteon can do to address the issue?
