CineXplayer on the new iPad: why does my avi movie "trembles" while playing?

Hi all,

I just purchased the CineXPlayer from the app store because I wanted to play a few AVI movies on my new iPad. I am really disappointed because the app couldn't handle the very first avi movie I threw to it.

The same AVI movie plays fine on my iMac using VLC. In cineXPlayer, the movie "trembles" but the sound is ok. Can anyone suggest where the problem might be?

I have removed cineXplayer and on the lookout for a free app for my iPad. Any suggestions?

regards,

Ali
