Lower bitrate on some channels?
 
Not sure if it's just me, my telly or a genuine change, but I seem to have noticed on a couple of channels (eg bid-up.tv) that the quality of the image has decreased.
It appears as if the data's more compressed, not to the point where there is obvious artifacting but just a little less sharp.
Does anyone know if this is the case?

Can you give some more examples Alan?

Well, also noticed it on price-drop as well, as those two partcular channels have lots of on screen graphics and I'd always noticed how sharp they looked in the past. It's a little difficult to compare on some of the other channels.

E4 is on half horizontal lines (that right?) on all platforms. C4 want to save bandwidth, I guess.

I think it's actually 3/4s horizontal resolution, but there was/is an issue with the Langley software which causes the vertical resolution to decrease too, giving a very bad picture overall.

I see this all the time. Especially when the pictures are changing rapidly. Sport for example.
