 I encounter the same problem too. Found out that it occurs
 when the vmult or hmult values are not 1, such as on my widescreen tv,
 and the the qImage->smoothScale function in NVP::DisplayAVSubtitle has to
 scale the picture to large dimensions. this creates a delay enough to
 cause the jerky picture.

 In my case the width and height are reported to be 1280  and  1017
 respectively.

 My CPU is a intel 2.4Ghz.

 investigating how xine and mplayer perform dvd subtitle scaling and see if
 this would be viable solution for mythtv.
