thanks, you're right, it works. when i start vdr it wants to tune a channel, and kdvb-fe process starting and eating 40-50% of cpu time, but f.e. mplayer works fine meanwhile. kdvb-fe thread active until vdr runs and eats CPU time (I checked with top) , but if I quit vdr kdvb-fe thread exists and free up CPU. so, it's ok here, where i have an activy with a rev 2.2 card, but without antenne (for development), but at home, where i have an antenne and Rev 1.3 card, it won't work. With antenne it won't eat so much CPU time, but mplayer stalls with HEAD, instead of kdvb-fe thread eats 1-2% of CPU time. Don't know why. Another strange thing with rev 1.3: I installed a 2.5.47 kernel with DVB drivers in it, and won't work stable, I switched back to 2.4.18 kernel, and make insmod DVB HEAD cvs, then dvbtune doesn't want to open dvb0 network device. Any idea? Maybe the 2.5 kernel modified something irreversible? (symoops, or something esle, don't know how i can debug) thx, basq -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
