"This is wierd." Topic

New TV has just one Scart socket (not got HD input yet, only got it yesterday). Thus I have a scart block into it, which the digibox and the DVD plugs into. The surround sound audio cables only go into the DVD.

Speakers->DVD-> Scartblock
Digibox->Scart block

Scartblock->TV

Got it?

NOW, here's the odd bit. The TV broadcasts afrom the digibox is coming through the S/Sound speakers (Not the rear 2). It stops when I take DVD out of the scartblock.

The DVD isn't on – plugged in but actually switched off (it doesn't have stand by), but somehow the sound is going through it.

SCART blocks are generally a bad idea. If it's a SCART switcher then that's a (slightly) better idea but most of those are not fully switched and isolating.

Most SCARTs pass through signals when the device is off for pass through purposes and there is no directionality as such on the socket, and so the sound from the digibox is being electrically connected to the output to the amp lacking a signal from the DVD player.

If your DVD player has SVideo out (or better, component) connect it using that to your TV instead.

If that's not an option then check to see if your digibox has twin SCARTs. If so, connect the DVD to the one probably marked as VCR and the TV to the one marked TV (obviously). This is the correct mode of operation for SCART devices in a serial configuration and should allow for proper pass through operation.
