Hi drappa,
Things do seem quiet, so perhaps a couple of controversial remarks will 
liven it up.

Several months ago I bought a USB dual DVB-T tuner (KWorld PlusTV) and was 
in a similar position to you, just a different model of stick.
With Windows, the job would have been straightforward, as Windows has an 
architecture for adding new USB products. A couple of entries in the 
registry, a driver for the chipset, and you're away.
With Linux, you've a choice of spending 35 hours trying to patch and 
recompile the kernel so that the new device is recognised, or if that sounds 
too onerous, wait 6 to 12 months until it's included in the standard kernel.

While I recognise that I cannot legitimately complain, since Linux is a 
take-it-or-leave-it arrangement where if there's a problem, I should ideally 
volunteer to fix it myself, I still do think that it's bizarre that a 
recompile of the kernel is needed.  I ask myself why it is not possible to 
have a database of devices (like the Windows registry) which can be easily 
updated.  This would allow simple installation of new products which use 
chipsets identical to existing supported products.

[The outcome with my tuner so far.... after a failed attempt at patching the 
kernel, I waited till 2.6.32 kernel was available, upon which the device was 
recognised, but still can only get one of the two tuners operating.  This 
will likely be the subject of a separate forum thread in the near future.]

Sorry I cannot shed light on your particular model of tuner.

I will conclude by saying incidentally, that I have been a very satisifed 
user of mythTV (with multiple PCI tuners) for the last two and a bit years.
