1213s with Firmware updates!

I found this site last night, and just started to experiment with the firmware updates. I have the Liteon 1213s, with the 1653 or 1633 firmware updates. I get no DVD playback, Powerdvd will either start and lockup or start the movie and lock up 5 seconds into it. Same with WinDVD. As for everything else it works fine. I can read DVD,CDs in the drive no problem. Anyone have a clue whats going on? I went thru all the patched firmwares for both, aswell as taking the stock one and modifying it all with the same result. only when I go back to my 1213s firmware does everything work like its suppose to.

This is my rig and specs

some drives don’t like crossflashing… yours could be one of them.
