[plug] dvdread problem

[Rob Dunne]

HI John,

I have uncommented

/dev/hda {
        dma = on
        interrupt_unmask = on
        io32_support = 0
}

in /etc/hdparm

(I already had dma on).I dont know what these parameters are doing but 
I seem to get less errors when copying
from the dvd (I still get some). More interestingly I now have mplayer 
playing a dvd!!

Just for good measure I am upgrading libdvdread as well.

Bye
Rob
