Default Re: Hedghog standards converter

Perhaps a stupid remark, but do the divider resistors in the video input have the correct value? R1 and R2 at resp 39 and 36 Ohms.
The IC has a very low supply voltage, and thus needs a low video input.
Also check the soldering. I found this the most difficult component in the Hedghog.
