Hmm, looks like you've reported the impact numbers from
GetDevice(). But I've wanted some log messages from
ProvidesTransponder().

Anyway, as the impact is the same for all devices, your driver
doesn't set DVBFE_DELSYS_DVBS2.

I've patched multiproto with the HVR-4000 support patch you've
mentioned on the linux-dvb mailing list.

cx24116.c contains this function:
/* TODO: The hardware does DSS too, how does the kernel demux
handle this? */
static int cx24116_get_delsys(struct dvb_frontend *fe,
        enum dvbfe_delsys *fe_delsys)
{
        dprintk("%s()\n",__FUNCTION__);
        *fe_delsys = DVBFE_DELSYS_DVBS | DVBFE_DELSYS_DVBS2;

        return 0;
}

Therefore the above mentioned flag should be set. Please check
whether this function gets called when VDR reaches the end of
cDvbDevice::cDvbDevice().

In case the emulation layer of the multiproto tree kicks in, then
the function will not get called and therefore DVBFE_DELSYS_DVBS2
is not set.

Bye.
