Could we eventually get to know what Media you are using? If they are crap, Powerec will slow burn process down to save your money.

i disable powerrec i get the same 2x speed.

Ist UDMA bei deinem System aktiv? Er hat mir einen G04 auch nur 2fach gebrannt, sonst jedoch 4fach. Kann damit leben.

udma is active but in the recorder have a jumper dma i need active this jumper?

Don’t close this bridge, it activates multiword DMA which is significanltly slower. This is meant only for compatibility reasons with older boards.

BTW excuse me for posting in wrong language!

Although your DVD-R media may be certified for 4x recording it doesn’t mean your Plextor drive will also write them at this speed. If you haven’t already you can try upgrading the firmware of your drive to the latest version to improve media compatibility. You can also check out the recommended DVD-R list for the PX-708A drive here.

i have the lastest firmware and the media is good i try it in a lite-on ldw400d and work fine in 4x.

Then all you can really do is wait for a new firmware upgrade which, hopefully, will allow your 4x DVD-R media to be written at this speed. Although your Lite-On drive does work at 4x it doesn’t mean the Plextor will too. I have some Princo 4x DVD-R media here that does work at 4x in the Plextor drive but I also have some MAM-E 4x DVD-R discs here that only work at 2x.
