When I am making playblasts of my animations, I am able to do it succesfully the first time but the second (and every other time) it only renders the first 10 or so frames then stops. If I restart Maya I have the same problem - 1st playblast is ok but after that it is a no go...

Could this be because of a lack of ram? I have 512megs. Or is there just a setting I am unaware of.

Thanks in advance for any help-
