vout echo port in soft codec sample

Need help trying to understand the SoftVideoOutputComponent sample. I compiled it in debug and ran it from SimpleVideoOut.

The SoftCodec_DrawBand function in the transfer codec is only called when I disable echo port no matter what I do? Why?

And when I do, SoftCodec_NewImageGWorld is called. What happened to the GWorld that the vout returned?

When the echo port is enabled, the codec is not used at all? What if I only supported the 'soft' pixel type, how would that work?
