Thanks again for your comments.

Yes, i plan to implement all the soccer rules but some of them not right now. I need to release a playable version stable and then upgrade it in phases.
About the avi file not working, i tested it just now and it works !
I would like to say too that the provisory name of the project was changed, because of possible copyright issues about the "droid" word.
I choosed "nŽdroid soccer" which was a ElloŽs sugestion, i hope he doesnt mind.
