picture quality on digital tv.. very 'blocky'
eg: watching I'm a celeb this last week.
I've a 2month old samsung 37" full HD 1080, watching through BT vision box.
now when watching ant & dec when they stand in the tree house area, the picture is cr&p and looks like mosaics have been put on the screen to get the picture, but when they show the camp area or any where else the picture is fine.
Also noticed when watching CSI Miami that on soom screen shots parts of the screen look blocky/mosaic-y.
Generally picture quality is very good.
Why all of a sudden will I be getting this, is it cus it's all digital?
as reverting to look at anologe tv its not happening.. but the quality of the picture is poor and colours not so good either.
anyone else get it and know what I mean??

BT Vision is downloading content for you to watch, it's all to do with compression and the codecs used to squeeze the content into something that doesn't suck up too much bandwidth.
Anything that's digital will at some stage have to be compressed in order for 10000's of people to be able to simultaneously watch on demand content.

I've also got a BTV box. It feeds the boosted freeview signal onto a 40" samsung LCD, so i can watch terrestrial digital TV either via the BTV or the TV receivers.
The BT freeview picture is quite a bit worse than the tv effort, so BTV is only used for recording plus its On Demand stuff and not the general TV watching.
I just assume that the BTV box isn't good a processing even a high quality signal than the inbuilt TV receiver.
Hopefully BTV mk2 will be improved.

Although as for the blocky water fall on celeb, its been like that since I can remember - even on a CRT TV via Sky. But I would have thought you would have already noticed that with your previous TVs.
Highly compressed Mpeg encoding falls to peices on: Fire, Waterfalls, Jungles and Football crowds or anything with lots of random motion that take a up a large area of the screen.

not tried the FreeView via the TV, funny ppl mention it happens on ITV more tha others, as BBC looks fine, glad it's not just me or my TV.
on IACGMOOH, it's mainly when Ant?dec are in he Jungle Tree house, once the camera goes elsewhere the picture is fine.
Also noticed it on some BLUray films.. like the recent RAMBO, again as mentioned when on the whole Jungle shots though!

Plus, recently, they have reorganised the Television spectrum with a view to bringing HD out. This reordering has reduced the bandwidth available for normal digital TV signals. The amount of reduction varies across channels and area of the country that you are in. This reduction increases the likelihood of digital artefacts (blocks) when scenes change quickly.
It will be a good idea to go onto the avforums and have a chat about what can be done to optimize your settings to see if you can do anything.
Otherwise you will just have to wait until all the digital change over is complete, and hope they allocate enough bandwidth to TV in your area
