Hi, > clean vdr1.0.0pre3 > patch with LiveAC3 > make .... AC3=1 ... you do not need the AC3=1 switch (at least I didn't use it, it's afaik for AC3OverDVB) > do i need two cards or shoud it work with one?? No it should even work with one, maybe it's a problem if the promary card is not DVB0. (You can't record & liveAC3 at the same time) Roland
