Fw: Kat5 Anomaly

[Gareth Cook <g@xxxxxxxxxx>]

Just take pin8 from the scart and send that into the TX unit with the
svideo signal - youll still get switching.

I did this before going full RGB

Hey Keith,

OK so I tried it on S-Video last night and it was slightly better. The
blue screen anomaly vanished.

My problem now is that I think I may stick to composite. If I use
S-Video I loose the ability for scart switching which at the moment is
an essential SWMBO component. If it's not done with one button press,
she is not interested :D

So considering that it's a composite connection is disconnecting pin 19
from the scart still valid ?

Either way, it's still a way load better than my old RF system :D So far
I am very impressed with the KAT5's. Great piece of kit.

Many Thanks

Marc
