I need s2 tuner and IP input (from the motherboard's Ethernet) and record them to file splices. Then (for request) i have to decrypt one or more ES from the recorded file and push them back. It's a DVB monitoring solution. thanks Balazs -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
