If you take that out of the equation, it seems like the only time there is corruption is when both the 115 and the x50 is encoding. So, it seems like we're back to either an RF issue or a DMA issue. Did David attempt to move the cards farther apart, or put any sort of shielding between the two cards? If the shielding has any effect, then we're probably talking about an RF issue. If it had no effect, then we are probably talking about a DMA issue. Either way, it seems like we should stop talking about the BER as any sort of indicator of a problem. Devin -- Devin J.
