Default Strange aspect ratio 'switch'

At 10 p.m. last night I went to Movies4Men 2 to watch Inglorious *******s.
It was at 16:9, which is unusual for that channel.
Realised after about a minute that I needed the +1, changed and it was 4:3
but too 'high'. Changed the TV to 16:9 and that was correct.

The set-up that I have is Auto-wide on the TV and 16:9 on the Freesat box;
this gives the correct ratio for WS programmes and switches to 4:3 for the
older films etc. It seems peculiar that the AR was OK on one channel but
wrong on its +1.

Do these film channels broadcast almost everything in 4:3? There was a film
on a couple of nights ago that was made in 2002, so I'd expect that to be WS
but it wasn't.

Sounds like they have not enabled AFD/AR toggling in the transport
stream on their +1 output, so your box didn't signal the TV to
automatically enter 16:9 mode ?

Interesting. On my TV (Panasonic) I have to set to 4:3 and then most things
switch to widescreen as required. It doesn't work the other way as if I set
16:9, everything is.

Yes, I wondered about that but it seemed a bit daft of them. I gave the
first channel a bit of time because I couldn't believe that it was in 16:9 -
thought that the switch might happen - then realised it must be correct if
the same film on +1 was wrong.

The Sammy has Screen Size (which I've set to Auto-Wide) and Screen Mode (set
to 4:3), but I'm not sure what effect the Mode has unless it is to go to 4:3
on the internal FV HD tuner when required.

As for FS: the box is set to 16:9 then, when on FS, the TV is set to 4:3 nad
that handles the switching correctly most of the time.

It's the same with the preset for the colour etc.: the FV box gave a lurid
picture so I switched to Movie and then adjusted to get a reasonable result.

The separate set-ups hold for each input device - if they didn't it'd be a
nightmare having to adjust every time. When I go to FS the settings
automatically change.

This is normal for Panasonics (although not exactly user-friendly).

to switching the aspect ratio manually.


Check to see if there's a pillarbox display option in the Panny HMDI
output options ? That's what I use on my Humax HD PVR. Any 4:3
transmission or channel is pillar boxed into a 16:9 frame, so the TV
does not need to switch, it remains in 16:9 mode regardless. The Humax
generates the black side bars.

Why thank you! There was, and it seems to have done the trick. I'd never have
thought it would be necessary to set the same thing up twice, and effectively
a different way for each type of output, switching the width in the TV for
SCART and in the PVR for HDMI, but it works. I'm also surprised that sending a
16:9 signal including blank bits at the sides for a 4:3 picture, which must be
wasteful, is the method used for the newer and supposedly superior system, but
I guess I'll just have to go along with what they provide. Less button-pushing
anyway.

The Sammy's manual warns against using cut-out display as the usual format
as it might have a permanent effect on the screen.
