This is the output of 'dvbtune -m' on C5 with > Athcool running: > > Signal=14135, Verror=11891, SNR=40349dB, BlockErrors=99, (S|L|C|V|SY|) > Signal=14135, Verror=13445, SNR=39578dB, BlockErrors=191, (S|L|C|V|SY|) > Signal=14135, Verror=12998, SNR=42662dB, BlockErrors=188, (S|L|C|V|SY|) > > And this is with it off: > > Signal=14135, Verror=1497, SNR=51143dB, BlockErrors=0, (S|L|C|V|SY|) > Signal=14135, Verror=1385, SNR=50115dB, BlockErrors=0, (S|L|C|V|SY|) > Signal=14135, Verror=1366, SNR=51143dB, BlockErrors=0, (S|L|C|V|SY|) On my system (Athlon XP 1800+, ASUS A7V333), athcool does not make a difference. The card is saa7133[1]: subsystem: 5168:0306, board: LifeView FlyDVB-T DUO [card=55,autodetected] In cz-Praha, I get the following regardless of athcool settings: Signal=40349, Verror=38170, SNR=65021dB, BlockErrors=0, (S|L|C|V|SY|) Signal=40349, Verror=43736, SNR=64764dB, BlockErrors=0, (S|L|C|V|SY|) Signal=40349, Verror=45370, SNR=64764dB, BlockErrors=0, (S|L|C|V|SY|) PS: Please CC me on replies as I am not subscribed to the list.
