Thanks Angelo,
That’s the first straight answer I’ve had about this topic.
I cannot find any PAL based guides for best practise in this area anywhere.
The reason I asked is that a while ago I was on a forum about something else and mentioned that I needed to crop the image to get rid of the bars.
Suddenly I had a load of replies stating that there was no need to crop and that I was doing something wrong. From then on it I was unable to find any further info about this.
Cheers again.
