I have created and burnt about 3 to 4 sliseshows since purchasing P2E and Ulead with no difficulty what so ever. Now Ulead DVD movis Factory 3 is saying that my file is not valid or the format is not supported. I have tried it a multitude of ways. with interlaced checked, with both interlaced and for ulead checked and just for ulead. Help!!! Please. Shelley
