My guess is this has something to do with the way the BBC broadcasts 4:3 
pictures.. they use something called AFD extensions which means they're still 
sending a basic 'widescreen' flag, but also describing that the picture is 
4:3 inside this - if the MPEG decoder doesn't handle this properly you end up 
with all kinds of squashed-picture or letterboxing-on-all-four-sides 
problems..

I don't use vdr-xine or other software decoding, so I'm afraid I'm unable to 
help here :/

Cheers,
Gavin.
