Hi,
I totally forgot about loader.conf, now the drive gets set to UDMA4 on 
boot. Its strange, but mplayer still fails on UDMA4, although I can 
mount the dvd no problem. So added the atacontrol command to rc.local.

Im sure the drive can handle UDMA4 since I remember that in Linux this 
drive worked perfect in UDMA66 + the manufacturer lists UDMA4 as a 
supported mode as well.
You're right. I have the same drive and it works perfectly in Windows at 
UDMA4 / UDMA66. I don't actually have anything else to add but that, so 
I hope you get your problem solved.

I havent been able to replicate the crash yet after a reboot, but if it 
happens I'll let you know.

Cheers

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?
    
It is a tunable as well, so set it in /boot/loader.conf.

 
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.
    
This is strange... Well, that the drive can't handle UDMA4 is not really
surprising, but you shouldn't see much issues with UDMA2.
*How* does mplayer crash?
