[linux-dvb] Re: AC-3 Support

["Peter Seyringer" <dvrproject@seyringer.priv.at>]

I doesn't know if this theme is allready discuss in the ml but is it posible
to implement an ac-3 live support? Someone tells me there are three posible
ways  to implement them. One is timeshifting. I think it would work only
with two card or to pack the ac-3 package into a PCM package or to change
the MPEG firmware. Is it posible to change the the firmware. I doesn't know
it realy but they change the firmware of the d-box I to implement the ac-3
support on this box.
