Hi tomasc, many thanks for your quickreply. I have tried all the menus provided, including Cinematic and Monopoly, and they all preview at 4:3. My screen resolution is set at 1920 x 1080, which is exactly 16:9, and I have tried different screen resolutions without success. I have also done some more experimenting, and find that though the output DVD plays ok on my standalone DVD / BluRay player, when played on any of three computers using various reply software, the menu appears in 4:3. It seems that the DVD player is compensating for the 4:3 menu and that the problem is with the output from Power Director. I have also noticed that when played on some player software including the latest version of VLC, the first few seconds of the edited footage stutters badly. This may be a completely unrelated problem however. Everything used to work fine with Adobe Premiere (on the same laptop), but I prefer Power Director and don't want to go back to Premiere, not least because it's very expensive and doesn't appear to do much more than Premiere, at least for my purposes. I could attempt to compensate by making objects (including the text) placed on the menu background narrower to begin with so that they stretch to the desired size in the output but I shouldn't have to do this, and in any case, this wouldn't help if my output DVDs were played on a laptop......
