module load order matters.  to explain how and why is beyond the scope of this conversation.  To make things easy, use "make unload" inside the v4l-dvb tree to unload all the media drivers.  (do NOT ever use make load)

The order that you loaded above will not propogate the debug=1 module option to tuner-simple, since you already loaded 'tuner' and saa7134 is already running -- the combination of saa7134 and tuner will automatically load tuner-simple without any regard to your command line module options.

try this:

make unload
modprobe tuner-simple debug=1
modprobe tuner debug=1
modprobe saa7134
modprobe saa7134-dvb

If the top input doesn't work, then try the bottom one.  Use the module options to change them if you like.

If things still dont work, then try the following:

make unload
modprobe saa7134-dvb
modprobe -r tuner
modprobe tuner

...that should do it.  Try both inputs.
