Hi All,

I was looking for a cheap USB DVB-T tuner available for pick-up in  
Canberra and ended up testing all of the cheap ones available at  
Jaycar. The short of it is that none of the cheaper ones work with  
Linux currently, there are some hybrid DVB-T and analogue tuners that  
are more expensive that I didn't try.

My setup was Ubuntu 9.04 with a pull of the latest source from linuxtv  
compiled against the 2.6.28-17 kernel. There are some useful  
instructions on this process at http://tom.mercelis.be/blog/nl/node/12  
on how to set the correct kernel headers and config.

Of all of the tuners I tried the KWorld usb stick should have worked  
but the chipsets have changed between the 395U and 395UR.

KWorld USB Stick II KW-D-395UR
USB ID 0x1b80:0xe39a
Not a recognized device although it runs an Afatech chip see

Digital TV Stick
This one would make a good project for someone looking to get into the  
v4l driver code, there are already quite a few similar drivers and the  
hardware is fairly cheap ($49). It has already been reported on the  
kernel mailing list (http://www.mail-archive.com/linux-media@vger.kernel.org/msg12792.html
