I have downloaded the match of Ivanovic - Zheng and it is horrible, impossible to watch it
It's hard to explain for me but in some words the pictures always "jump" so impossible to watch it.
I can read all matches I have downloaded to date, why this one don't work!
I have not an other computer so it is impossible for me to know where come from the problem
First which file did you download. Is this the set of links:R2.Ivanovic.X.Zheng
Second, you didn't tell us how you play the video. What media player did you used? Which part of the video was giving you problem, was it the entire video? etc, etc...
I've got to be honest here... If you don't some sort of information, nobody will be able help you, however much they liked to.
I've download those links above to check for you. It seems to be playing fine.
