I have a DVB adapter https://www.linuxtv.org/wiki/index.php/TerraTec_Cinergy_T_USB_RC and I use w_scan to generate channels.conf it works fine under Fedora 24 (default kernel) but not under Exherbo (hand-made kernel) mpv can, on both systems, use the good channels.conf (from Fedora) I can paste the failing w_scan output if needed can it be a kernel-side error or only a w_scan error? SardemFF7: what's the error you get? also, it might need some firmware, check `dmesg` firmware is ok, dmesg is the same under both systems https://gist.github.com/sardemff7/013940f52e3fcf51a6c7bbcca37b9408 hmmm, w_scan has a recent update, didn’t see that, I’ll check this one it updates so rarely I forgot to check… let’s see SardemFF7: the log shows that it has found a transponder (498MHz), locked on it, read some data from the stream. etc. updating worked… sorry for the noise ^^ thanks anyway, bye np
