Thank you for the reply, today I managed to download correct codec and now ti works like it should. Thank you again!

I have a similar problem, accept I use DVB-T USB 2.0 stick Twinhan. After I installed the ProgDVB, this message always appears that there is some error and the program must close itself. And this always happens if the signal is weak. But if the signal is strong, there is again some anoying message ...
