I know this has been discussed before and we gave them a bit of a pass as it was 'new' to them, but really it's time for them to sort their sh*t out I think.
Just today, I happened to be flicking through and saw that they were broadcasting a TV show with both letter-boxing and pillar-boxing, and *still* the resultant image was in the wrong aspect ratio -- tall and skinny.

What are they doing? They need to get a clue. Even their own idents and self-produced ads are all over the place - some with letter boxing, some with pillar-boxing, many with the wrong aspect ratio, or a combination thereof.
Come on, Living Channel. Even if your source material is 4:3 (and why on earth are you still buying and/or showing programming that is so old it's 4:3 anyway?), you should be zooming or cropping or both - not postage-stamping. If you are going to postage-stamp, at least make sure the end result is the right aspect ratio. In other words: sort it out!!!
Rant over.
