DVD Trouble

When i play a DVD in xine, the dvd lags pretty bad under both the 2.4 and 2.5 kernels. CPU time is at 100%. Also, when i make any change (pause, fast foreward, etc.) i lose all sound anbd have to quit and restart xine.

I tried ogle, but it quits w/ an insufficant resources error as soon as it starts.

I have a decent com (p3 6500/3230mb ram) and have previously watched DVDs w/out trouble, however i may not have watched any since updating to gentoo 1.4 if i could have broken something there.

EDIT mplayer /dev/dvd returns the exact same error as xine

maybe try to turn on udma manually
at least check to see if it's on, it wasn't enabled at first after my install...
got me pretty bad lag too, but now everything works like a charm

Besides the UDMA, a good tip would be to mount the DVD before reading it, the mplayer folks say that it improves velocity :-)

This is usually a dma issue as was already mentioned but also make sure you're using the xv video output driver in mplayer.

If all the above suggestions don't help, make sure you are not using software video scaling. That can eat lots of CPU cycles just making minor changes to the video window's size.

Look at /etc/init.d/hdparm. By default the script enables DMA for hard drives only !
Edit it and add a line to fit your needs.
I had the same problem and this is the way I solve it.
