Re: problem with second tuner on Leadtek DTV dongle dual

Performance issues are fixed recently (at least I hope so), but it will 
took some time in order to get fixes in stable. Unfortunately I don't 
have any IT9135 BX (ver 2 chip) dual device to test like yours...

Could you install that kernel tree:
http://git.linuxtv.org/cgit.cgi/media_tree.git/log/?h=devel-3.17-rc6
and firmwares from there:
http://palosaari.fi/linux/v4l-dvb/firmware/IT9135/ITE_3.25.0.0/

and test?

regards
Antti
