 When setting the DVD player in myth to use "internal", I notice that DVD
 playback is not smooth.  The video playback speed oscillates somewhere
 between 0.6x-1.4x the sound is usually unbroken and 1x.  The problem is
 most obvious on a smooth pan during movie playback.  Playing the same DVD
 using mplayer works fine with solid 1x playback.

   As another member on myth-users had pointed out: playback in mplayer
 causes the DVD-ROM drive's light to be steady -- always on, while playback
 with the internal player causes the drive's light to constantly blink.
 It's as if the drive is not streaming the data continuously.

   mplayer also has a -cache function which can be used to increase the
 amount of look ahead buffer on the DVD.  The internal player may benefit
 from such an addition (if it doesn't already exist).
