Hey,

I've just obtained and installed a new DVD Burner (NEC ND4551A) which supports 16x DVD+R burning.

When burning a data CD (around 4.2gb of files and documents) onto one DVD+R, it comes onto the progress screen showing the "Maximum Write Speed" and the "Current Write Speed". Even though my maximum write speed shows 16x, my current speed doesnt increase over 5x   .

I am using DVD+R certified to 16x speeds, i have over 1gb of RAM and plenty of free hard disc space. What could be causing the speeds to remain so low?

P.S. When burning the same items using another program (Nero 7) the disc was burned in less than 5 minutes (when compared to 22 minutes with Roxio Media Creator 8).

Thanks

EMC burn engine totally relies on the burner to properly recognize the media in the drive so having updated firmware is important.  Although the drive can burn at 16X, it can only burn at that speed if you have a blank DVD that is certified for that speed. If you purchase blank media certified for 4X, then it should burn at 4X. Some applications like the one you mentioned will ignore the certified speed of the blank media.  The EMC burn engine queries the DRIVE each and every time before it burns. The drive tells EMC what speeds (which is encoded on the disc) the blank media can be burned.  Burning at a faster speed than the certifed speed can result in a poor burn or unreliable burn.

Is Nero and EMC 8 installed on the same machine? If so and Nero burns faster dma must be enabled. Nero is defaulted to max burn speed. What media are you useing? Make and speed.
Get a disc identifer like dvd identifer. cddvdspeed, or dvdinfopro free download google.
Then look at the disc and note write speeds and media ID should look somthing like this. Verbatim MCC 03RG20,  4X 6X 8X 12X 16X. These are the certified write speeds of the disc. But bad media can be misleading, shouldn't be but it is. There's fake media with fake certified burn speeds. Need to know what your working with.
