I've been trying to get the ATSC tuner in my KWorld PC120-U PCI Hybrid ATSC (17de:a134)
Are you sure you don't mean the PC120-U ? -- I can't find such a product. A PC150-U model, on the other hand....

Is > the "digital channel decoder" different from the digital tuner?? > Should be looking for a different chip? they are detected by chip IDs. The tda8290 is the IF demodulator for global analog TV. In case of the saa7135 it is an extra chip on the PCB, which most often can also control the tuner over an i2c gate. The tda18271hdc2 is a global hybrid tuner for analog and digital terrestrial TV. It can also provide a FM radio IF. Further processing and stereo separation for that is done on capable bridges like saa7133/35/31e, not on the tda 8290. Yes, for any terrestrial digital TV you need an extra channel decoder and all known details about it. http://linuxtv.org/wiki/index.php/Category:ATSC_PCI_Cards In case of terrestrial ATSC, it must be able to deal with 8VSB modulation.
From the pics on newegg ( http://www.newegg.com/Product/Product.aspx?Item=N82E16815260032 ), it appears that they have used a Samsung demodulator
