Totem & DVDs - stutters a bit when not on battery

[dave]

Ok, well, tonight I noticed behavior more similar to what Vincent is
experiencing than what I'd seen previously. Even plugged in, I was
seeing the stuttering.

Since I'm running totem-xine, I checked out Xine's FAQ and found this:

http://xinehq.de/index.php/faq#AEN201

I checked my cdrom and lo and behold, no dma. As soon as I enabled dma
on /dev/hdc, the stuttering disappeared.

Just wanted to post a follow-up for posterity.
