It won't take that long, regardless of the speed you choose. Using the 
DVD R/RW and media shown below, I burn a double-layer DVD in ~25 minutes.

Drive:  TSSTcorp CD/DVDW TS-H552B GA04 Removable CD-ROM
Blanks: Verbatim DVD+R DL DVD

The most useful piece of information is reported by cdrecord:

# cdrecord dev=/dev/hdc -prcap
...
  Number of supported write speeds: 1
  Write speed # 0:  2770 kB/s CLV/PCAV (CD  15x, DVD  2x)

So the write speed is 2x.
