Brian Butterworth published on UK Free TV What you are seeing is one of the two problems that are well know about the "MPEG-2" system that is used to encode digital TV.
Because of the way the system works, horizontal movement across a crowd requires a disproportionate large amount of data to encode.
Because the bandwidth on Freeview is so limited, and as most broadcasters have decided to have more channels rather than better quality pictures, on most channels the bandwidth is so limited that the effect you see, a blurry mass of blocks is visible.
The sceptical will say that this is simply an excuse to sell you HDTV equipment and channel packages.
The other problem you will see is when strobe effects are used - this will often look like very large black and white boxes.
If these effects trouble you, do not go out and buy yourself a massive TV as they will be simply much clearer to you.

I think what I am trying to say is that the A/V amp receives the stereo signal and reproduces it as 5.1 or DPL11 automatically. However if BBC sends the signal as DD 5.1 but it is actually stereo then the amp doesn't recognise it so 3 of the 5 speakers are left empty. Obviously if the signal is 5.1 there is no problem.
It is the centre speaker that handles most of the content and fixes the voices to the TV screen, but when listening in two channel the voices are kind of just floating around and not co-ordinating with the screen which would happen even if you just used the built-in TV amp/speakers.

David Haworth: Yes, and I have said already if you select the receiver to be in "stereo" mode rather than "dolby" mode then you will be able to process the stereo into whatever you want.
And as I have also already said PLII had to be selected by you as does not have either INBAND or OUTBAND signalling.

My god your up early!
You still have not confirmed whether BBC sends out a signal that seems to be labelled 5.1, confirmed by the display input on the A/V receiver,but is actually stereo, which I believe is the heart of the problem.
Listening to dialogue without a centre is a totally different experience and sadly missed when it isn't there.
Obviously this only applies to Freesat HD which has the ability to broadcast in 5.1.

Thought I would add my son's comments.
He's correct that given a stereo feed, you have to select PL2, and your
onkyo does this for you automatically so you don't need to.
What I'm saying is that I think BBC1HD is broadcasting some shows in 5.1
but where the centre, rears and sub channel are silent. Ie they should
be broadcasting 2.0 so that the onkyo can choose to apply PL2
processing, but by sending a stereo feed in 5.1 (where L,R have content
but not C,SL,SR,Sub are silent) they're doing it wrong.
Whether you can force PL2 processing on a 5.1 feed I don't know... And
what it would do when you get a real 5.1 feed I don't know...

Thank you for reading my problem. My Matsui HD ready TV has a built in freeview receiver but the free hd channels do not come up during any scan for channels. No mention is made about whether these free HD freeview channels are watchable on this TV via it's own receiver in the manual for the TV. Is this due to the TV and it's receiver or something else. the ariel is on the roof and reception of signals is very good. The TV is 18 months old. Thank you

I have an analogue tv connected through a digital tv box.This produces a decent picture. I have now bought a new 32inch digital TV. the picture quality particularly on peoples faces and on outside broadcasts , football racing etc, appear to be blurring at the edges. What is the cure ?

P.JONES: Check for 'sharpness' settings in the TV's configuration menu - though usually they come configured with too sharp a setting.
A new TV will usually have a native HD resolution, and have to upscale SD broadcasts, so some blurring is inevitable as the screen resolution is not an exact multiple of the SD picture's resolution. Again, worth seeing what options are available to correct this.

I'm on freesat with a Humax Foxsat pvr, and whilst the Humax Diagnostics show 100% for both Signal and Quality, I am getting "blurred" pics particularly on SD.Is this an alignment problem with the Dish. I've tried different TV settings. Should "sharpness" control be high or low? although it seems to make little difference.

David Harold Constantine: Turn sharpness off.
But yes, the pictures will be blurred in SD, that's why HD was introduced.
I presume you are using an HDMI cable from the box to the TV?
