I did try, but somehow i must say that the DVBs card at least _can_ show 
every X-Resolution - but however it does not always fill my TV Screen :-(

For example i have a movie with 624x272 - using the above scaling leads to 
624x334 - calculated correctly !
But when viewed on my tv i have black border at the right of my screen and 
the apect ratio isn't that good !
However i have played around with some values - and for me it seems that 
there are only some certain values for fullscreen X resoultion - among them 
are 480, 528 (btw. MTV broadcasts this way) 688 and 704 and 720 - others 
might work too - but strange enough: 640 produced the same black border as 
624 did !

Conclusion: Using scale=688:0,dvbscale did work fine ! Maybe dvbscale should 
fix to these values ? (or at least my script should do :-)

Can anyone confirm whis behaviour - or is it a strange phenomenon on my 
particular DVBs card / driver / tv set ?? Maybe some x-files ;-)

btw: I use a DVBs 2.1 Card from Hauppauge and the DVBs driver from 01.04.2002!
