Does your bppc have a recent flash-rom which recognises the bvppc ? Does the Amiga screen appear on the bvppc output, even without drivers ?
Get a recent flash update from here:

Erm, now that i mention it, do you perhaps have Picasso96 installed with the Mediator ? If so, you have to uninstall it. P96 and CGX cannot be mixed.
