Yeah, Donald.

In DTV, you could argue that 1280 X 720 or 1920 X 1080 are 1:1, as you (Donald) 
say. But in fact, those wide screen formats are called "anamorphic," I'm pretty 
positive, because they stretch out what was traditionally a 4:3 TV frame into 
16:9. They do not achieve 16:9 by cropping a 4:3 frame, rather by stretching it 
out horizontally.

I'm saying, Jeroen, that when the TV signal is transmitted in these formats, 
i.e. 1080i or 720p, I can't make my TVs or my STBs zoom in correctly, ever. So 
for example, if that 720p or 1080i content happens to be postage stamp, I must 
view it that way. This is exactly the same problem experienced by Cliff. He 
cannot zoom in on anamorphic 16:9 (which contains 4:3 pillarboxed content).

And by the way, this is also true for these 1080i or 720p signals when recorded 
on my Philips SD PVR. You'd think, with HD recorded as SD, I'd be able to zoom 
in correctly in playback. Nope. Only if I record 480i subchannels can I then 
zoom in as expected.

Oh, okay, so somehow you made it work now.

So here's the deal, Jeroen. What always made 16:9 an attractive choice was that 
we knew, even before 1994, that before too long, most new TV programming would 
be adopting this aspect ratio. So even if you had to watch a lot of pillarboxed 
content initially, the situation would rectify itself in due course.

With 21:9? Aside from the DVD or BDs of 2.35:1 (letterboxed) movies, will TV 
productions be migrating to Cinemascope format anytime soon?? Or may this just 
be the choice for 2.35:1 movie aficionados?
