1.1       holger      1: Troubleshooting - or the most common problems...
                      2: ------------------------------------------------
                      3: 
                      4: If you encounter any troubles building and installing the driver you might
                      5: want to check that the following prerequisites are satisfied:
                      6: 
                      7: You must have the kernel sources for the kernel you are currently using
                      8: installed, and symlinked to /lib/modules/$(KERNEL_VERSION)/build. This should
                      9: be the default in proper installations with installed kernel source package.
                     10: 
                     11: If you are in doubt please get a fresh and clean kernel source tarball from
                     12: http://www.kernel.org/, unpack, configure, install and boot this one before
                     13: building the DVB driver. 80% of the bug reports on the linux-dvb mailing list
                     14: have been related to not properly installed kernel source trees in the past.
                     15: 
                     16: For cards with MPEG decoder onboard make sure that CONFIG_VIDEO_DEV is enabled
                     17: in the config of your running kernel. If you get unresolved symbols named
                     18: video_XXXX when loading the driver then you missed this option.
                     19: 
                     20: For some cards you need Input and Event Device Support enabled to get the
                     21: IR receiver on the card running. Be sure to enable CONFIG_INPUT and
                     22: CONFIG_INPUT_EVDEV if you get unresolved symbols named input_XXX.
                     23: 
                     24: For bttv cards you need a recent bttv driver installed, this is either part
                     25: of the kernel or available as standalone driver on Gerd Knorr's website
                     26: (http://bytesex.org/). Also you need to explicitly enable i2c and i2c bitbanging
                     27: support in your kernel for those cards.
                     28: 
1.2     ! holger     29: If you get a message 'insmod: no such device' while loading the driver - don't
        !            30: worry, this is normal, since you load the drivers for all possible cards some
        !            31: of the drivers complain because they don't find a matching card in your system.
        !            32: You can safely remove those ones from the list in the insmod scripts.
        !            33: 
1.1       holger     34: If you are sure that all the issues above don't cause your problems you might
                     35: want to ask on the linux-dvb mailing list for further assistance
                     36: (http://www.linuxtv.org/mailinglists/).
                     37: 
                     38: good luck,
                     39:
