   Would like to be able to use my dvb dongle in Slitaz. The kernel isn't recognising it or laoding any drivers for it. Under Xubuntu it sows as follows:

   lsusb
   Bus 001 Device 002: ID 1b80:e395 Afatech

   dmesg
   [ 14.812122] dvb-usb: found a 'KWorld USB DVB-T TV Stick II (VS-DVB-T 395U)' in warm state.
   [ 14.812323] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
   [ 14.876096] dvb-usb: schedule remote query interval to 500 msecs.

   OK made progress. Found the v4l-dvb package in the stable 4.0 repository: v4l-dvb-development_2.6.37.tazpkg, installed rebooted and dvb dongle found and modules loaded.

   Problem now seems to be with usage. Mplayer and Mplayer-SVN seem to have so many options disabled that the "mplayer dvb://" command is killed. This also prevents any more activity in the terminal window (?).

   Looks like I'll have to compile mplayer from source ?

   This is where I have got to so far, following guidance from the Linuxtv wiki:

   1. Firmware copied over from Xubuntu
   2. Modules loaded for dvb-t dongle
   3. dvb-apps installed from source
   4. Trying to run anything (e.g. scan) against the dvb-t device results in a "Killed" output
   5. Although v4l-dvb is installed and apparently working from slitaz cooking, attempted installing v4l-dvb from source, but this fails as Slitaz doesn't have "lsdiff". If it does, where is it?
   6. Double checking against xubuntu install everything seems the same, but just doesn't want to work.
   7. Lots of errors pop up in dmesg after trying to run a dvb app

   Here is dmesg output on bootup:

   WARNING: You're using an experimental version of the DVB stack. As the driver
   is backported to an older kernel, it doesn't offer enough quality for
   its usage in production.
   Use it with care.

   and here it is after running mplayer dvb://

   can anyone point me in the right direction?

   About the Warning, and from the Linux video input infrastructure (V4L/DVB) development discussion and bug report mailing list:
   Since the migration to -git, less developers are using the -hg tree. Also, some
   changes are happening upstream that would require much more than just compiling
   the tree with an older version, to be sure that the backport won't break anything,
   like the removal of BKL.

   As normal users might not be aware of those issues, and bug reports may be sent
   based on a backported tree, add some messages to warn about the usage of a
   backported experimental (unsupported) tree.

   So the driver may be buggy, in unstable condition or working well, we don't know but It seems to load pretty well.

   Maybe some udev rules are missing (I'm lazy, I didn't check) so /dev/dvb is not fully populated?
   You should see a folder hierarchy under /dev/dvb which looks like this:
   

   # ls /dev/dvb
   adapter0
   # ls /dev/dvb/adapter0
   demux0  dvr0  frontend0  net0
   #

   Thanks for responding dom
