I've recently shelled out the fee to enable the Pro part of Quicktime. And now I've a question. Select/cut/paste are available in AVI files (Divx5 codec I think it was) but the options are all greyed out for an MPEG1. I've seen nothing in the documentation that suggests this difference should exist. Does anyone know what gives here - can QTP not edit MPEG1 or is something stranger happening?
