Aero disables itself every time I start DVDFab, then re-enables when Fab exits. I get a pop-up at the bottom of the screen telling me it is going to do this every time. The pop-up tells me it is doing this because of incompatibility or low resources. I have one GB of ram, but that still might not be enough on this OS. I thought maybe it was the interface of DVDFab that is incompatible, because I don't get the message on progams like Nero which is definitely a memory hog and it doesn't disable itself with Nero.
