I have Avermedia A177 with twin tuner. All versions since 6.46.05 (last working properly) recognise my card as a satellite card and won't open it. Scanning doesn't work properly ...only open two channels on same network ..not different network channels. About time you got it right

Try set Settings->Device Options->User only one tuner at once.

Now with 6.49.4 everything seems to work again except Dual tuner. Up to 6.46.5, I could have two dual tuners (Avermedia and KWorld) and open 4 networks at once or multiple stations on one network. Now I cannot get multiple networks (the main purpose of dual tuners).

Try check "Use only one tuner at once" in Device Options.

It doesn't work for me
