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...

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 :-)

Maybe he still has an SDTV and doesn't realize it? ;-)

And of course the HDMI carries the audio signals as well.
