I've tried setting up my mum's Avant so that the AV input connects to her digital terrestrial decoder, and the Decoder input connects to her DVD player. However, when I view a DVD through the Decoder input, there is a faint flickering of colours, mainly red and green. This is only noticeable against pastel backgrounds, and doesn't happen when the AV input is used. The DVD player offers two output formats, which it calls SCART and CVBS (or something like that). Each of these displays the same problem via the Decoder input.
For now, I've had to daisy-chain both devices to the AV port, but I'd rather that when mum presses the DVD button on the Beo4, the DVD input is selected.
Any ideas?
If it helps:
Avant 32", Model 84/23,
SW(AP) 3.2,
SW(FEP) 2.1,
SW(STB-C) 2.1,
TABLE(STB-C) 1.1.
Also, as an aside, I'm aware that the system software is rather old. Is it worth upgrading? I know that an STB-C upgrade would allow use of STBs less than 10 years old, but what would an upgrade of system firmware do?
As always, thank you in advance,
Mark
