What DVB CARD do you use? If you're using one of the TechnoTrend "budget"
cards, try 188*1024, since that is the "chunk size" in which the hardware
delivers the DMA buffers. With 256*1024, you're requesing one DMA buffer
and a fraction of the next, and since the DMA is somewhat time-critical on
the budget designs, especially on your relatively slow 450MHz CPU, that
might cause overruns.
