I'd think so, too. Without LNB power there's not much you can do, anyway... > > > There are some mandatory delays before and after sending > > > the DiSEqC sequence.

Sendeing DiSEqC codes in VDR is done via the ioctl(fd_frontend, FE_DISEQC_SEND_MASTER_CMD, &cmd)); call - is this no longer the way to go?
