The approach of splitting the parallel RGB planes to separate streams didn't work for me, i've decided to use the polyphase scaler to do my pre-scaling filtration and I'll determine my co-efficients later on - right now I'll use the presets. I'm using a post scaling sharpen filter now and I couldn't get that to work in parallel either with the re-sequencer! I'm now resequencing to serial as my bandwidth is far lower after scaling. In serial I can use the 2D fir natively and problem solved.

Sorry I can't shed more light on the approach... i've got to move on before I get sacked!
