On the menu bar on the tv screen it reads '576i' (on the right) although on the settings menu of the stb it reads 1920x1080 interlaced (?)
I understand all this means that the program you are receiving is 576i, and the settings menu on the lower picture just changes what the STB sends to the TV over HDMI.
Thus, the picture is being upscaled by the STB which isn't going to make it any better. You can't make HD out of SD, or in more down to earth terms, you can't polish a turd... Upscaled SD is often a disappointment on HD TV sets.
To say something about the picture quality, you need to change to a channel that actually broadcasts proper HD material, I don't think SVT24 does.
