I'm trying to play DVDs using xine and it is very jerky. After
searching on google, I noticed that a lot of people say to turn DMA on
for your DVD drive. However, when I try, I get the following error:
[root at localhost linux-2.4]# hdparm -d1 /dev/hdd
/dev/hdd:
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
using_dma = 0 (off)
Is there some other way to turn it on. I'm thinking that I will need to
recompile the kernel, but I'm not quite sure which setting I need to
turn on. Here's my system:
[root at localhost linux-2.4]# uname -a
Linux localhost.localdomain 2.4.18-14 #1 Wed Sep 4 12:13:11 EDT 2002
i686 athlon i386 GNU/Linux
