BBC Three HD aspect ratio

I watched a bit of 'Family Guy' on BBC Three HD last night and noticed
it was 4:3. I checked BBC Three SD and it was widescreen. Is there
any technical reason for this, I wonder, or was it just an error?

was 4:3 the right shape? - for older episodes it should be.
i often find the hd channels show 4:3 correctly while the SD one won't
unless you have chosen to set your tv to 4:3 mode.

Family Guy was only recently changed from 4:3 and some repeats are
quite old.

I appreciate that, but how would that explain 16:9 on SD and 4:3 on HD
at the same time when the same episode is being shown?

Was there any geometric distortion on either version (hard to tell with
Peter Griffin !) In other words was the 4:3 version a centre crop ?

Both last night's episodes were very early ones, and would have been
made in 4:3. I saw about a minute of one of them on the HD channel,
and it was correctly displayed. I didn't look at the SD version.

Well, I've never seen WSS signalling of 4:3 mode on HD channels,
4:3 progs I've seen seem to be presented with broadcaster added
side bars. If you think about, all HD screens are 16:9, so there's
no requirement for WSS on HD ?

Perhaps on SD the Beeb forgot/failed to signal 4:3 mode, and
the result would have been a stretched image, filling a 16:9 screen ?

My Panny plasma recommends setting the sidebars to some mid grey rather
than black for extended 4/3 viewing, which of course is not possible
with broadcast pillar box.

I did not look closely enough, unfortunately. Next time I will be
more observant!

Indeed not, though 4:3 programming probably offers fewer burn in hazards than
the bright captions and tickers that plague some channels ?
