Does ShowShifter support DivX Pro 5.10?
Not at the moment. ShowShifter 2.10 (the latest version) comes with version 5.03, if you have version 5.10 of the DivX Pro codec already installed, ShowShifter will not recognise it. To workaround this, you can create your own recording profiles in ShowShifter to use whichever version of DivX you have.
