Dear Dave,
Thank you for your reply.
When I press render (in render view) the image won't show up. Not when I render as a AVI, JPG, TIFF or anything else. I have tried it with different settings for format, etc, however the image still won't show up.
However, the images are being rendered (I deleted the files before I pressed render) and when I open the files using native windows applications, they show up and display as I would expect.
I'll check if they can be displayed using FCheck and try to update my video drivers and get back to you!

Thank you in advance,

Ps. I'm using Maya 2012 PLE
