I'm trying to render a simple particle scene consisting of 500 frames for testing.

If I play the animation just within Maya everything works as expected. If I render any given frame from the RenderView using Hardware Rendering, it renders fine and as expected.

I have set my RenderGlobals as shown in the attached file, but all that happens when I go to Renderout the animation to .TGA files in the BatchRender icon, it only renders 10 frames instead of 500 and even worse, the 10 frames it does render...it renders as and AVI!!!!

What is happening here?
