Thanks for the help. Yep I made a mistake. It was 352x576 that it was
recorded in. The audio was 44100 though. In my settings for my ATI
software, that is the preset for DVD half resolution recording (HHR)
and full res is 720x576 (CCIR-601) but still saying 44,100 as the
audio frequency! This must be a fault with the ATI software, so I
will just have to make new presets with it as 48,000.
Thanks for the help and links
