Well. That unfortunately also doesn't compile:

g++ -c -pipe -Wall -W -O3 -march=pentiumpro -fomit-frame-pointer `freetype-config --cflags` -D_REENTRANT  -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -DPREFIX=\"/usr\" -DMMX -DUSING_DVB -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -I/usr/share/qt3//mkspecs/default -I. -I../../../../include -I../../../../local/include -I../../../../include/linux/dvb -I../libmyth -I.. -I../libavcodec -I../libavformat -I../libdvbdev -I/usr/share/qt3//include -o dvbchannel.o dvbchannel.cpp

Which shows the problem with returning -1 from a constructor you
mentioned before, I believe, and again the possible namespace
problem (line 436).

Since fd_frontend and fd_sec are defined as parts of the DVBChannel
class, using them without further specification in global namespace
(which the DVBTune function is), seems responsible for the problem.

As DVBTune seems to be one of the few functions in that file that are
not part of DVBChannel, it is easy to see how this could happen...

Georg
