I tried to cook up something - but I'm not sure if frame rate for PAL 16:9 progressive should be 25 or 50 ...<br>

> Although currently there is no labeling standard, DVDs with content <br>
> originally produced in an aspect ratio wider than 1.33:1 are typically<br>
> labeled "Anamorphic Widescreen," "Enhanced for 16:9 televisions," <br>
> "Enhanced for widescreen televisions," or similar. If not so labeled,<br>
> the DVD is intended for a 4:3 display ("fullscreen"), and will be <br>
