I cant burn DVDR's faster than 1.30x or something like that. cdrecord says:
cdrecord: DMA speed too slow (OK for 9x). Cannot write at speed 16x.
hdparm says:
/dev/cdwriter:
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
readonly = 0 (off)
readahead = 16 (on)
I dont understand why it is like this. DMA, 32-bit is on. Its using a
Promise TX2 UDMA/133 card. Should be enough. LG GSA-4120B is the burner
model.

The burner is on hde. I use FC4 (2.6.10-1.770_FC3smp).
Anyone got a idea?
