Thanks for the feedback Stephen. I have an Asus EN9400GT Silent. I think 
it should do 60 Hz. I found a similar (identical?) web page 
(http://www.mythtv.org/wiki/User_Manual:JudderFree) to the avenard one 
and I did have a bit of play but no joy so far.

Pretty sure my TV (Pana Plasma) will do 60 Hz but need to check this and 
then xorg config and then yada yada .... Sigh. I banged my head against 
refresh rates a couple of years ago when I first set up MediaPortal on 
Vista (cringe).

Certain the video is 30fps or probably 29.xx Hz NTSC. It's from my camera.

Haven't got MediaInfo but ffmpeg say 30fps.
