Maya 8 resolution problem

[PowerDeo]

Hey all,
Im doing Maya 8 for about a month now and im making progress quite fast BUT after im done with my work and if its a picture i can render it at any resolution i want. But when its a video i can only render it at 640*480 . And that is very irritating because yea the resolution is very low then.
Please can someone help me with this one

That's very odd. Are you using some type of limited demo license software that may preclude you from high res renders?

What about rendering a picture sequence at a desired resolution? Typically picture sequences are used more often that Quicktime or AVI video.
