Also at:
http://people.freebsd.org/~nox/dvb/linux_dvbwrapper-kmod.shar
If anyone can test it, even the better! :) (Still seems to be
working here with the Linux w_scan on dvb-s2.)
Thanx!
Juergen
PS: If anyone is wondering why this is a port now, one of the
header contains lgpl'd parts out of the Linux dvb headers and
I got no reply from the author of those parts... :(

XThis kld adds DVB ioctl handling to the Linux compatibility layer
Xso that Linux apps can talk to DVB/ATSC tuners via /dev/dvb/adapterX.
X
XNote this port does not contain actual DVB drivers, those are
Xprovided by e.g. the multimedia/webcamd port.
