@s-island: Hm, I'm not sure. But I suspect it's to do with subtitles rather than an NTSC/PAL thing - the .til files are still 640x480.
@bgbennyboy: Put emphasis on 1280x960 - the videos are fullscreen, the backgrounds scale the nicest and the save thumbnails display properly. For different resolutions though, remember the fix to black out the background when a video is playing. Thanks heaps
Still looking for tools to work with the voice files...
