$ dvd+rw-mediainfo /dev/dvd INQUIRY: [PLEXTOR ][DVDR PX-712A ][1.05] GET [CURRENT] CONFIGURATION: Mounted Media: 1Bh, DVD+R Media ID: YUDEN000/T01 Current Write Speed: 8.0x1385=11080KB/s Write Speed #0: 8.0x1385=11080KB/s Write Speed #1: 6.0x1385=8310KB/s Write Speed #2: 4.0x1385=5540KB/s Write Speed #3: 2.4x1385=3324KB/s ...
Yes, the media advertises itself as 8x. But it may be defective. Or the drive may not write properly at this speed. The short answer is - most probably bad media.
Now I see it's a bit more complicated. The label clearly states 1-4x speed (an image is at http://www.maxell.eu.com/, unfortunately there is no direct link to the web page) but the Maxell's compatibility list states that Plextor PX-708A can use 8x speed. New DVD drives, namely my Plextor PX-712A, is not listed there. The Plextor's web page http://www.plextor.be/technicalservices/technology/recmedia.asp?choice=Suppo... states that Maxell's DVD+R(4X) can be written at the 8x speed. So the information provided by dvd+rw-mediainfo was correct. I'll try to burn one more DVD+R at the 8x speed.
Anyway, I'm puzzled where the 8x speed comes from. Is it stored on the disc or does the firmware provide the speed? It guess the latter is true since some drives can only use the 4x speed.

It seems it comes from the firmware. At least I remember reading something like this on growisofs site, regarding some speed change problems they had with plextor drives and bad media database. Sunny -- Get Firefox http://www.spreadfirefox.com/?q=affiliates&id=10745&t=85
