NeedHelp: Slow burning speed when burning DVDs using Roxio8

Im having trouble getting my DVDs to burn any higher than 1.5x, Im using HP DVd+R 16x discs, my drive is ‘HL-DT-ST DVD±RW GWA4164B’ 16x… Im using Roxio 8 to burn. I tried the DMA check method already, any other suggestions? thank you.

A simple google search on your drive shows numerous users having problems with burning. Have you tried upgrading the firmware?

the fimware update available from dell is useless in regards to this particular issue, any other suggestions…

Is having the same symptom with other burning software?
