I was already planning to build one of those when I got the
chance - apart from anything else the only spare S-Video input
on my TV is on the front but I have a spare RGB SCART input
on the back.

I was looking at the nexusuk circuit, but the sput.nl one looks
the same anyway. Time to pay Maplins a visit I think...

I realised that the RGB output would be better but I didn't think
the S-Video output would be quite as bad as it is - like I say the
S-Video output from the DVD player is not bad at all. Certainly it
is much better than composite while the S-Video from the Myth box
looks no better (and maybe even worse) than the composite output
of a normal set top box.
