NTL whats with the black edges?

[sda]

My Sony KV32FX65 on some channels has black sides ( the right bigger than the left ) which are constantly bending and bowing!
Now before you say KV32FX65! when I plug my ariel in I get a perfect picture??
Is this an NTL problem?

I get a similar problem with my KV32ls60. A black bar on the right of the screen. But this only happens on BBC channels ( not all the tome though) mainly teletubies (dont laugh).

This is a known NTL problem, in so much as the Pace STB’s do not centre the frame correctly hens the shift to the left, so you end up with a wider black line on the right. You only notice this when the Beeb show marital that is smaller than 16:9 so that the picture cannot be stretched across the width of the screen leaving (what should be equal) black lines.
