Once you're in a Channel callback you have native access to the GL driver as 
you would expect to. I'm assuming you're using the Eq GL context to setup the 
FBO? Some small code example and the related error would go a long way...

The roiFinder FBO setup is relevant in the sense that it works setting up an 
FBO. The eqPly AccumBufferObject also uses an FBO internally.


HTH,
