I checked it in another computer .. same problem!
Did anyone ever hear of such a behaviour?
I could backtrack my problem it now to the last firmware-update: before the upgrade from 1.37 to 1.39 it worked fine with the CDs .. I used the official Firmware from Pioneer: DVR110D_FW139EU.EXE
is there anything I can do? Cleaning the lense or sth ..
And another question:
How does pioneer handles guarantee and upgraded firmware? And if I use DVRFlash to flash it back to 110D .. is there a chance for pioneer to see all the upgrades that were performed?
