Shinzy: It should say on the PS what it is rated at. The ones i have used have been 18v @ 300mA but obviously i cannot say for certain what yours is.
I have 24 volts on the downconvertor side i think this is right. I have also went to mates house yesterday that has Choru$ and my digivox box is working. Ill try again the weekend and see how i get on. Thanks for all help.
