Thank you for your input.

Guess nuke it is. I have been using Playblast to view my sequences and also plain old Fcheck to compile my image sequences... Just realised I'm wanting to start dipping my toes in the next step, but had no idea what 'pool' that was... seems to be a half a dozen choices or more available and I couldn't/cant find a good way to distinguish between them. (without actually trying them all)

Thanks again.
