This is only true for the DV format. All analog capture cards capture at a 768x576 resolution for PAL sources, because this keeps the correct aspect ratio. If you want to convert the captured image to a DV stream, you will have to transcode it ( or capture with 720x576 but there might be cards which do not support that format ). But there is no real reason to do so unless you want to write a DVD because all other formats like AVI can handle other resolutions than just 720x576. -Arne >
