Re: [pygame] video error

["Jason Massey" <jason.massey@xxxxxxxxx>]

Is the entirety of your code in your __init__ class?

I'm not sure if the spacing got mangled in the e-mail but the way it came across when I cut and pasted the class into my editor is that your while loop is in the main Class, not in the __init__ function.  Since the class gets created before the __init__ is called that's what's causing your problem.
