Ahoj, prestehoval jsem se a zjistil, ze mi nefunguje MythTV. Pokud pripojim TV kartu ke spolecnym antenam, tak nenajde zadny kanal. Musim rucne dodefinovat transporty, zastrtnout „Ignore timeout“. Pak mi sice najde vsechny kanaly, ale nefunguje mi pro ne EPG. Vlastne nefunguji vsechny dobre. Dost casto se totiz stane, ze kanal nelze prehravat. Pritom pres Mplayer kanal praje bez problemu – sice cas od casu nejaky ten obraz, ale jinak v poradku. Divne je, ze pomoci utility dvbscan stanice najdu…
Nevite nekdo, cim by to mohlo byt? Diky za rady.

Petr StehlíkZlatý podporovatelŘekl bych, že je to sílou nebo kvalitou signálu ve společných anténách. Zkuste vlastní anténu.

Nevim, jestli je to zrovna tim. V puvodnim byte (a take spolecnych antenach) jsem mel signal tak 50–54% a MythTV fungoval, resp. nasel jen CT. Ted jsem to meril pomoci utilitek (test kvality DVB-T) a nameril jsem:

Ondřej CaletkaZlatý podporovatelTenhle signál je naprosto v pohodě. Pro zkoušku si pusťte třeba kaffeine, ten umí i EPG. Chybu bych hledal v konfiguraci MythTV.

Ahoj,
tohle vypadá jako problém popsaný na české MythTV Wiki: http://wiki.tvpc.cz/mythtv/zname_chyby_a_workaroundy
Zkuste, snad to pomůže.

Tak jsem smazal kompletne celou databazi MythTV, vytvoril novou konfiguraci. Pokud nezadam rucne transporty, tak nenajdu zadny kanal. Import z channels.conf nefunguje.
Po nalezeni TV programu (celkem 14) a jejich ulozeni, MythTV v bash vypise:

Doporučuji se spojit s ostatními uživateli přes web www.tvpc.cz. Do mailing listu jsem teď posílal patch pro DVB-T, se kterým snad musí fungovat full scan všem i bez zadávání transportů.
A vůbec nevím, co si myslet o tom pádu mythfilldatabase, nicméně EPG by mělo fungovat i bez něj. Ovšem proč je u všech kanálů channum=14?
