BenQ 1620 and Ritek G04

I have a 50 pack of Ritek G04 DVD-R media that I wish to use with my new BenQ 1620 until Best Buy puts the Fugi DVD+R 8X on sale. Any experiences out there with this media and drive?

They work ok, not great in my 1620 with B7T9 fw. However its limited to 4x burn without using MediaCodeSpeedEdit.
