Hello, I have a system with two Hauppauge Nova-S-Plus cards and a HVR4000Lite. Very often I'm getting errors like: cx88[0]/2-mpeg: general errors: 0x00000100 cx88[2]/2-mpeg: general errors: 0x00000100 Digging in the code, I found that is DMA related, meaning TS overflow. Looking further, I found that for TS handling, FIFO queue size is really small, only 4K, of available 32K. As long as the DVB-S2 streams are running up to 80Mbps, isn't this value too small a fluent running ? I presume that these overflows are caused by larger PCI latencies, causing delays in buffer transfers. As long as these cards are used most of the time for TS handling, isn't there any chance to increase the TS FIFO size ? Or optionally allocating more for this purpose ? The HVR4000Lite has no video or audio inputs, but there are allocated resources for them, wasted resources.
