> But I guess demuxing is necessary to get the "NIT(actual) table", isn't it ? Generally speaking applications configure the demux to pass all pids, so yes - the demux is typically mandatory. Data is received from the dvr0 device. Assuming the card is tuning and delivering complete unfiltered transport payload reliably, then if no NIT is appearing then I can only assume either the application isn't waiting long enough, or it doesn't existing on that frequency. - Steve -- Steven Toth - Kernel Labs http://www.kernellabs.com -- 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
