Interesting. I *watched* the snooker, and it didn't appear to be in 
widescreen. (Or maybe that's just FreeSat?)

There seems to be a great lack of the sciency type of programs I like 
these days. We used to have great shows like Rough Science, Scrapheap 
Challenge, Local Heroes, Horizon, BBC Wildlife, etc. Now there's just 
Brainiac... which is rather lame.

Yeah, that's how the VGA output usually works. (I have that also, BTW.)

Yeah, but I meant, HDMI is encrypted. I'm not sure whether the laptop 
really supports generating an encrypted video signal, and if so, from 
*what*...?

I watch it via my Sky box (that's the same signal as FreeSat isn't it?) and 
I certainly didn't notice any stretching (it would be quite obvious in 
snooker because there are lots of perfectly spherical objects in view all 
the time).  What made you think it wasn't widescreen?

Scrap heap challenge was good fun, but it got a bit annoying when they 
obviously planted useful stuff.  Like "oh look there's a complete working V8 
engine that's just lying here under this rusted car shell".

The lack of black bars at the top and bottom of the screen on my 
grandparent's 4:3 CRT. Maybe they were there and I just didn't notice? 
Certainly when you watch a 4:3 signal on a 16:9 screen that's errantly 
configured to distort the image, it's pretty damned noticable!

Yeah, well, that part of the show was *sliiightly* tenuous at times. But 
the whole concept of "OK, we need to mash together a machine to do X... 
how the hell do we actually do that?" was really neat.

Unfortunately the show slowly drifted from being about the science to 
being about the personallity clashes, differences of opinion, mutinies, 
etc. that I don't give a damn about. Why is it that today everything has 
to be about "reality TV"? Just get on with the engineering!

Oh, on my Sky box if you tell them that you have a 4:3 device connected it 
chops off the sides to make a 4:3 picture from a 16:9 one.  Some programs 
that I see (I think that Snooker might be one of them) keep all the 
important detail (ie the scores, any graphics etc) in the central part of 
the picture, so that those watching a 4:3 chopped image don't miss anythign 
important.

I have never noticed this, either my Sky box is zooming 4:3 streams to fill 
the screen, or it's just there are no 4:3 streams that I watch.  BTW, it's 
quite common that 16:9 streams have black bars top and bottom as well to 
give an even wider aspect ratio, don't assume the presence or absence of 
black bars says anything about whether it's widescreen or not.

Yeh it was cool to watch them making things, I really like that sort of 
stuff.  Just a shame I don't have room at home to make a nice workshop, one 
day though :-)

Agreed, although haven't watched it recently so it might be worse now than I 
remember!

Not forgetting the channel logo (if it has one - another great thing about BBC),
which can be really irritating. I wouldn't mind if that got chopped off *at
all*.

And the "coming up next..." bars which obscure the critical action at the climax
of a movie. Those grind my gears even more. :)

Ah, actually... I do seem to recall the picture coming up briefly on the 
TV, and then it flashing something about "auto" and the picture changing 
shape. So yes, I think the TV itself cut the edges off. That'll be why then!

If it's just set to cut the edges off, it's not too bad. If it's set to 
mash the picture to the wrong aspect ratio, it looks terrible!

If you're watching it on a 4:3 screen and there's black bars, it's not a 
4:3 aspect signal. What aspect it *is*, who knows? But it's not 4:3. ;-)

...fortunately...for the safety of the world... ;-)

Who can forget the Barley Pickers and their "propper job" of building a 
machine that ****ed itself apart in the most spectacular way possible 
the very first time they tried to use it? :-D

Well, there always was a social element to it. And that was part of what 
made it cool. But now they emphasize it too much, and don't talk enough 
about the engineering. There's a little Big Brother-style "confession 
booth" where team members can go in and be like "well I though it woz a 
good idea, right? But Dave, he says, right, leave it how it is. Well I 
mean that's silly, innit?"

Dude, like, who cares? I much preferred it back when it was a team of 
mates who'd mistaken the "build machine X" task for a "weld as much 
stuff as humanly possible" contest.

I feel it all went wrong when that girl presenter left...

Not always.  DVI can be encrypted too.

Does it have Vista?  If so then yes it probably does, for example if you 
connect a bluray drive (eg via USB if you don't have one in there already) 
and try to play a movie.  There is probably some API in Vista if you are 
writing a game and want it encrypted output for some reason.

Really? That's interesting. I was told this is the defining difference 
between HDMI and DVI.

I was *going* to buy the laptop with a BluRay drive (it was only £10 
more), but it sold out before I could order it. *My* laptop has only a 
DVD drive. (And yes, obviously it's Vista. It's impossible to buy 
anything else now...)

I guess they hadn't seen the monitors that accept HDCP over DVI?  Or the 
DirectX10/Vista graphics cards that have HDCP capable DVI outputs?  Or the 
Wikipedia page on HDCP for that matter :-)
