Handbrake issue

Having a small problem with handbrake, after having ripped a dvd into .avi format i attempted play the file but it would not work in Quick time? I have the relevant codec in order to be able to play .avi extensions and have tried quick time with other files and it works perfectly?
Any info on what the problem is would be greatly appreciated

Try using VLC player, it pretty much plays everything. If it doesn't work in that, then you may have a corrupt file or messed up some setting somewhere prior to encoding.

Cheers i will managed to sort it out by just ripping it in MP4 format which seems to work perfectly in quick time, i will deffo try VLC player next time i have this issue though.
