It uses a Empia em2820 chipset, and a Tena TNF-9533-D/IF tuner. Other chips I found under the casing are: > RM-KUB03 04AEAAC6, HEF4052BT, TEA5767, SAA7113H. I have a device with similar chips. All of them are supported. TNF9533-D is PAL, afaik. > (I had to manally tell modprobe to set the card type (18) and tuner type (61), as it does not have an EPROM. Took me forever to figure that out! It is possible to add some autodetection for it. Are you using the driver at http://linuxtv.org/hg/v4l-dvb, right? On its dmesg log, it will print some codes that helps to do some tricks for detecting it, based on I2C scan signature. > The problem arises when I try to do anything with it, though: I've tried a few programs, including mythTV, tvtime and xawtv. I can't find a way to select the TUNER as the input source. The only options are "composite1" or "s-video1". It seems that you're selecting a different board type. > I tried cycling through input=1 through 4, but they didn't work either (2 through 4 give an error about the card not being able to set its input). The proper procedure is to run an usb snoop tool that allows us to know what is the pinup of certain generic entries used to select between tuner/composite/svideo. > The only thing I can think of, is that the tuner may actually have originated outside the USA (i.e. the UK). Would that stop it from working with NTSC channels? And even so, should the composite input not still work? (And why can't I even select the tuner!?). The tuner won't work properly in US, since the analog filters inside the tuner is different. Composite should work fine.
