Havent used Pico psu yet,  but do you have access to a multimeter?  

If so I would check the output on the  +5v, +12v, & -12v power lines.   The amiga just needs those with GND to be happy rjust make its getting supplied with that at a suitable amperage

Its probably the small square inductors causing the RF Noise on the Pico PSU..

Hmm I guess try and make a metal enclosure for the Pico PSU and for the Svideo adapter  if possible..

Also you might want to put a RF Choke (ferrite bead) on cables going to/from the Svideo Adapter  (http://en.wikipedia.org/wiki/Ferrite_bead)

The video cable is probably acting like a big antenna for RF noise from PSU..

Also how about wiring in the Pico PSU in a small box in middle or near power plug end of cable perhaps using the original Amiga power plug.   Try and keep it far away from the unit.

Let us know how you go?
