The blue colored are version 1.0, but on green colored I can't find
version number anywhere on PCB. I will try to remove some labels, if it
I replaced green one with other blue card because I have total 5 blue
cards. I wold like to get 4 of the to work for my new mythtv setup. And
then to setup another slave mythtv backend for other two.
I tried your advice with this lines in /etc/modprobe.d/options
options dvb_core dvb_shutdown_timeout=0
options bttv i2c_hw=1,1,1,1 card=0x71,0x71,0x71,0x71
options dst dst_addons=32,32,32,32
With these lines I can get to work three cards of 4 (all ver 1.0 and
blue), but I can boot my system just 1/3 times. Other 2/3 of boot
procedures system just hangs.
