Good evening Vlad,
Thanks for reply - yeh they're there - sorry just pointed VC at them and alls well. As to the matter of a valid conversion setting - I've solved that as well.
If you have a 720x576 original video for conversion with a XVID codec, the 'original' option gives you a frame size of 768x576, which is not a 'correct' xvid setting. Hence no matter what you try, it will not play on a XVID machine. Perhaps with your next update, you might ensure that original means original!
Regards,
Chris Carter-Bown
