Re: [linux-dvb] cx88-dvb: fix nxt200x rf input switching broke my tuner? :)
Hi, I've notice the same thing with my Kworld ATSC-110. I'm running Ubuntu 7.10, 2.6.22-10-generic, x86_64. I guess it is a change in the 2.6.22 kernel. Is there anyway to change this back so that QAM and NTSC inputs are the same?

Re: [linux-dvb] cx88-dvb: fix nxt200x rf input switching broke my tuner? :)
CityK, Thanks for your reply, but that is not what I'm seeing in MythTV and TVTime for /dev/video0. I'm getting signal from /dev/video0 when I use the upper input, not the lower one. I haven't trying tuning 8VSB, but as for the QAM input, that seems to be working as expected. Maybe I should look at the driver config for input select in SAA7134 or swap the input selection lines for VSB and QAM in the dvb code? After looking at the input selection code in nxt200x.c, QAM and VSB, it looks like if I switch these lines it will swap the inputs. //QAM - state->config->set_pll_input(buf+1, 1); + state->config->set_pll_input(buf+1, 0); //VSB - state->config->set_pll_input(buf+1, 0); + state->config->set_pll_input(buf+1, 1); Am I correct? I am confused as to what these lines do if (state->config->set_ts_params) state->config->set_ts_params(fe, 1); <-- what the front-end parameter 0 or 1 mean.

Nathan, Please do not top-quote As per your description above, you are correct... HOWEVER, now I understand your issue -- you are running old code. If you update to the latest v4l/dvb modules via linuxtv.org mercurial, you will find that functionality has been restored as per your desire. Please see http://linuxtv.org/repo ...for instructions to upgrade your v4l/dvb modules.
