Hi Igor,

Small question. I tried your patch, but it fails a hunk in dvbdevice.c. I
added this hunk manually but I think something is missing:

Sep 28 13:56:15 htpc vdr: [19486] ERROR (dvbdevice.c,251): Operation not
supported Sep 28 13:56:15 htpc vdr: [19486] ERROR (dvbdevice.c,252):
Operation not supported Sep 28 13:56:15 htpc vdr: [19486] ERROR: frontend
0: Invalid argument

Those both lines has the following code:

CHECK(ioctl(fd_frontend, FE_SET_VOLTAGE, volt)); CHECK(ioctl(fd_frontend,
FE_SET_TONE, tone));

The result is, no tuning and no picture.

And to be honest, I don't really understand why it shouldn't work. Mainly,
since the same code is used with the Kaffeine patch (I'm comparing that
also).

Any help is appreciated :) If you need a quick chat, I'm currently in
#linuxtv on irc.freenode.net :)

Regards,

Niels Wagenaar
