First, please try not to top post...

I stuck with 16436 because that was the original value in the kernels that
didn't give problems.  I figured if it was not broke I'd stick with what I
knew would work.  Since I made the change I've had none of the stuttering
issues at all.

I'm not sure what is causing the issue with your other .iso files however.
Myth has always been somewhat buggy when it comes to DVD playback.  VLC and
xine are typically flawless but the same files choke MythTV.  I've started
ripping almost everything to .mkv files because of the headaches with .iso.
