[ILUG] finally perfect DVD in linux.

[Gavin McCullagh]

Well, perhaps not perfect, but if it drops a frame it's every ten minutes
or more.

	I still had a problem on my P2 400MHz with some number of frames being
dropped say a few in each 200.  Watchable, but irritating.

	Anyway Nick mentioned Ogle and I was having a look puurely out of 
interest with no intent to try using it (AFAIK you need hardware acceleration 
for a system of this speed).

	Glancing at the FAQ:

31. Playback is choppy. What can I do?

Check with hdparm if you have enabled the DMA of DVD-drive.

	I feel mildly stupid not to have thought of this.  But anyway, this
was the final problem.  Now Windows and linux play DVDs with equivalent
quality.  Now all I need is my ATI All In Wonder Video output to be
supported in X and I can hook it up to the tv.

	It does surprise me that none of the other docs I've seen mention
this as a potential problem.  After all, how many people actually use
hdparm?  I also managed to triple the throughput of my Hard Disk which is
nice.
