Ed Matlock suggestions “a more elegant way is to flash your DVR’s firmware to region 1 using DVRFlash 2.1.1. I have flashed many Mac’s and the results have always been excellent. Another benefit is you usually get a speed increase in both reading and writing (Apple is notorious for crippling the hardware), plus you’ll find your media is more compatable (meaning media that won’t burn at higher speeds will). Pioneer DVR’s will also have the ability to do DVR-RAM”.
“If you look around, Pioneer DVR-111D (40xCDR, 16xDVDR, 8x DVD DL)can be found for around $40. Flash it to DVR-111 to add DVR-RAM.
“Use PatchBurn4 and all your iLife apps will see it.”
