Here is an exerp from an oops I got after closing mplayer, watching an ATSC (dvb in USA) stream, using AverTVHD a180 (saa7134 + nxt200x).

Email me if you need something else... I'll be around for the next 5 hours.... After that, I will be away for the weekend, and I can do more tests on Monday evening. This was on an intel p4, 2.53 GHz, 533 FSB, 768 MB ram, using Intel D845PEBT2 motherboard. -Michael Krufky -- Michael Krufky - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
