BTC DVDRW 1008 0159 Firmware

Just bought a PD rebadged BTC 1008 and went to drvupdate.com to get the updates. After flashing with 0159, it seems the drive will only burn at 4X for DVD +R media. I used nero infotool to check the drive and the only burnspeed that shows up is 4X and 2X… The media I’m using is 4X, does this affect nero? Anybody else have this problem?
If I can’t figure it out, I’m taking it back tomorrow and exchanging it before the rebates expire.

try a 8x media. and yes, nero & infotool will report the burning speed based on your media

thanks for the info.
