This makes the demuxer very slow. The 'scatter-gatter voodoo' is a better solution. If exist a function, which can allocate cached continuous physical memory, you should replace pci_alloc_consistent() with this function. - Hartmut _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
