Hi, Just to report that I can lock on those problematic transponders with kernel 2.6.37 (and with an amp on the coax of 40m long), but not with 2.6.39-rc6. I figured the patch which might cause my problem is the following [media] stb6100: Improve tuner performance [http://git.linuxtv.org/media_tree.git?a=commitdiff;h=f14bfe94e459cb070a489e1786f26d54e9e7b5de] I recall that in this thread [http://www.mail-archive.com/linux-media@vger.kernel.org/msg29712.html], there were concerns about the above patch. Is it possible to remove it from 2.6.39 release and do further research or is it too late ?
