I have been rendering some old projects out using Main Concept mp4 for my Nook Tablet (1024 x 600). When I render VBR, all is well. When I render CBR I get the message


An error occured while creating the media file NookCBR.mp4
The reason for the error could not be determined.


I flip between VBR and CBR with otherwise identical settings (project settings 720 x 480) and the error is repeatable.

Anyone else?
