I don't have any insight to the problem, I'm just adding that I have the same problem.
Hitachi V47 flashed with GaryOpa 2.2
I'm having problems playing backups of COD3 and GOW.
COD3 plays for a a bit (30min to an hour) then will finally crash which loading a map (30min into the game or so). Upon a reboot I get the 'unreadable disc' error.
GOW bites the dust right after the Game rating screen.
If I let the xbox sit for a few hours, it will allow me to play again for a short period of time, at which it will then repeat the errors above. "Unreadable Disc"
I'm interested in checking the POT and/or buying a new/replacement laser.

POT tweaking the Hitachi is exactly the same as the Samsung. The drives are nearly identical, physically. Once you get to the laser head, use a multimeter (set to 20k Ohms) to chech the resistance, and adjust the pot accordingly. A lower number results in a stronger laser. Tuts I've seen say don't go below 2.8, but mine's at 2.5 and working great(the actual pot for dvd calibration broke off, so I've got the CD pot jumpered to it so they share the same value). I'm not worried about burning out my laser, cause I've got another
Do you use the same points to tweak as in the Samsung guide?http://dwl.xbox-scene.com/tutorial/XBOX_36...1.0_by_Moda.pdf
