I've had a similar problem before where the frontend was detecting the
screen refresh rate as something like 49.97 (rather than 50) and
deciding that the display couldn't cope with bob.

To confirm, you'll need to check your frontend logs (-v playback).

If true, the 'easiest' way to fix it is to slightly modify your
modeline so that the timings calculated by X/mythtv are give a refresh
rate >50Hz.
