Greek Channels Scan Problem

Post by bekiaris » Thu May 10, 2018 7:12 am

Dear all,

i set up myth tv. My card is wintv-hvr-5525 HD of hauppauge. Although in cafeine i can scan channels with success and see live tv without problem, in myth tv i can not scan channels successfully. i found also this patch greece-dvb-t.diff #8070, but i do not now how to use it. First of all, in general should i use pal system or sth else? i put in input East European.

I increased the timeout time in scanning however, still no results from scan tool of mythtv...

i found this ->https://www.mythtv.org/wiki/Command_Lin ... el_Scanner

There is a special frequency table for every country, also in Greece i should use in command line
dvbt-ofdm-gr -> Scans Over-The-Air broadcasts in Greece
So, i should use ./mythtv-setup.sh --scan dvbt-ofdm-gr ???

After some search and help from lists, i insert the trasports manually through backend UI and after that i scan only for existing trasports, so i manage to found 47 channels.

The transports are the following, for Greek channels.

ysql> select * from dtv_multiplex;
