ITD1000 is just the "tuner/PLL" (or how the thing is called in DVB-S) Depending on the board it might be possible to do more with it (LNB-power ...) but I don't know. > I want to be upfront . . .

Writing support for the tuner would be a good thing and if you have the bbti-driver you should have all you need to do it. The thing you got from BBTI is just a linux-dvb-fe-wrapper to their Demod/tuner API, I think it is not much sense to put this somewhere, but it would be better to have dvb-tuner-ops-driver dedicated to be used in linux-dvb. > What do I need to do? I hope I'm going to answer your question: I remember that the PN1010-demod was having a strange tuner-i2c-behaviour: after a stop-condition you need to signal to the demod that there is more to do (the itd1000 is connected to the demod-i2c-connection to limit the i2c-traffic-spurios'). Maybe putting an i2c-adapter inside the s5h1420-driver is a first start to have communication. After that you can write the itd1000-driver. As a template you can you mt2060 or any other module which implements dvb_tuner_ops. Then you have to see how close the current s5h1420-driver is to the pn1010-driver used by bbti and merge it so that support for existing devices is not broken. I have two sample of those cards, if you want I can help you in testing and writing some code, but I'm going to have some vacation before :) .
