well, what does the picture looks like in P4 ? I don't think it comes from your PC bit-depth - 16, 24 or 32 bits is the same for P3dO all pictures are uncoded with 32 bits depth. I would need the original .rsr file and I'll have a look at it. But first show me how it should look like. White should be transparent I suppose. yarp@senosoft.com btw New P3dO release 1.5.3 has an editor with alpha channel - available at SENO. You can copy/paste both the picture and alpha channel though being able to see what P3dO does.
