I love election nights. You hear rational, logical, fearsomely clever people like David Butler spouting rubbish like "If swing across the country follows east London, it'll be a Tory landslide. If it follows the north west, it won't" to fill the yawning gaps between results. Both statements were true, but about as useful as "If swing across the country follows Mr Arnold Qunt of 3 The Larches, Toxteth...".

Oh joy! A namecheck just now for Bill Boaks.

Something I've noticed before, though. As far as I know, it's standard BBC practice to transmit 4:3 material in a 16:9 frame, sending a flag to digiboxes to crop the pillarboxing at the sides. However, the 4:3 material always seems to be off-centre, with a little picture information being cropped at the left of the screen. During a recent Jazz 625, Humph introduced Art Blakey from the left of the picture with half of his body off-screen. BBC Parliament isn't bothering with the flag, so you can see it quite clearly - the left pillarbox is narrower than the right. I'm recording on one machine in 12P16, with the other set to 4:3 centre cutout, and a little picture is being lost. Is this everyone's experience?

No, I've just taken a look on DTT using the TV's own tuner, and an external Topfield PVR, and all is well. The curtains are the same width. Same looking on D-Sat from a Humax box via HDMI.

However, are you sure your problem isn't because of RGB/composite delay over scart interface. TV sets extract the sync pulses when in RGB mode from the composite video line of the scart connector. The set top will have a PAL encoder, fed from the RGB outputs of its MPEG decoder. The encoder often introduces a small delay on CVBS, relative to the RGB video signals, therefore the picture as displayed will shift slightly to the left as a result.
