Hi!

Valgrind told me that:

==18266==
==18266== Syscall param ioctl(generic) points to unaddressable byte(s)
==18266==    at 0x1D569544: ioctl (in /lib/tls/libc-2.3.5.so)
==18266==    by 0x1BF6EF71: DVBChannel::Tune(dvb_channel_t const&, bool) 
(dvbchannel.cpp:550)
==18266==  Address 0x1 is not stack'd, malloc'd or (recently) free'd
==18266==
==18266== Invalid write of size 4
==18266==    at 0x1D0E73C8: QDateTime::currentDateTime() 
(in /usr/lib/libqt-mt.so.3.3.4)
==18266==    by 0x1BF6EFAB: DVBChannel::Tune(dvb_channel_t const&, bool) 
(dvbchannel.cpp:553)
==18266==  Address 0xFFFFFF0F is not stack'd, malloc'd or (recently) free'd
==18266==
==18266== Process terminating with default action of signal 11 (SIGSEGV)
==18266==  Access not within mapped region at address 0xFFFFFF0F
==18266==    at 0x1D0E73C8: QDateTime::currentDateTime() 
(in /usr/lib/libqt-mt.so.3.3.4)
==18266==    by 0x1BF6EFAB: DVBChannel::Tune(dvb_channel_t const&, bool) 
(dvbchannel.cpp:553)
==18266==

which attached patch works around in addition to removing a ugly cast.
