Hey guys,

I'm pretty stumped on this. I have a stock Mandriva LE 2005 installation, and I'm trying to play a DVD in Kaffeine. The problem is, it's really choppy. When I try to enable DMA on the drive, I get the following error:

Code:
[root@dhezir dhezir]# hdparm -d1 /dev/dvd

/dev/dvd:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma    =  0 (off)
It's a SATA drive, so that's probably what's causing this. Could I get some help with this? Thanks!
