[MPlayer-users] DVD divx playback not smooth..?

[Daniel Kenzelmann]

Check with hdparm if your DVD is in UDMA mode.

hdparm -I <dvd-device>

[...]

Capabilities:
        LBA, IORDY(cannot be disabled)
        DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2

[...]
The Asterisk shows which mode is used .. if it shows something like
"PIO"... then you have to change to DMA mode with:

hdparm -d1 <dvd-device>
