medialand supertv bt878

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi, i have a bt878 tv card that isnt mentioned in the cardlist, i havent
tried anything except the tv functions, (havent tried teletext or radio)
and there are a few other cards that work, avermedia is the one im using
at the moment.

The only hitch is that audio is reversed, i.e. when any TV viewer is set
to mute i can hear the tv, when audio is set to on i hear nothing. Its
not a major problem or anything, it is mildly annoying that whenever i
boot up the audio is on by default os i get load static hissing...

Anyway, is there any way of reversing audi, i dont think the medialand
supertv is a very popular card, but if you do want it in the cardlist im
prepared to some more testing.

Here is some info about the card.
