Dvd,dvd,dvd...

[Petr Janda]

Mine is set to 0. SO I did sysctl hw.ata.atapi_dma=1 and it says:

sysctl: oid 'hw.ata.atapi_dma' is read only

Why is that?

atacontrol has shown me that the device was in PIO4, so I set it to 
UDMA4 instead(which is what my drive should be using as it supports it), 
but then my dvds couldnt be read so I tried UDMA2 and it improved it 
heaps though not perfect, and it seems that mplayer seems to crash more :S.

dmesg shows:
acd0: DVD-R <PIONEER DVD-RW DVR-109> at ata1-master PIO4
Is this an indication that DragonFly perhaps needs a more modern/recent 
ATA code?

Cheers.

Xine looks horrible(and skins dont work) and xine menus behave very

watching dvds in mplayer is unwatchable (skips many many frimes). Ive 
never had similar problems in Linux where dvd playback was always smooth.
    
Check that hw.ata.atapi_dma=1 is set. Otherwise you can active it with
atacontrol as well.
