Holy cow! the thing tunes fast now! One burst error I received seemed much more devasting to mplayer's decoder than it usually does though. (I guess fast tuning or relocking may have it's disadvantages, but decoding errant streams as sanely as possible is more a software decoder's problem.) Propagation conditions here today are much better than in recent days due to weather changes (it's close to 50 F!). I'll test tonight around sunset and later when things get colder, to get more more data points for what happens when burts errors occur. But right now, it looks very good. :D Regards, Andy > Thanks, > > Devin -- 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
