See, that is totally wrong (or rather not as right as right could be) methodology. The real secret to picture perfect tv-out is to display to the TV _exactly_ as the original signal would have. Record the signal exactly as it comes and display it back exactly as you recorded it Don't post/pre-process it because of a crippled TV-Out method. So you record the signal field by field and then redisplay it clocked perfectly, field by field. That is the only way to do it. This is what DirectFB and the G400's TV-Out accomplishes. Unfortunately, Myth's use of QT makes this impossible because QT does not support DirectFB, or even SDL. SDL would be satisfactory because SDL supports drawing on a DirectFB surface. b.
