It makes sense to write a separate module like you suggest, because otherwise we would be writing TUA6034-specific code from within tuner-core or dvb-pll or cx88-dvb or something else... And this wouldn't cut it, because the LG H062F / TUA6034 / LGDT3303 combo also appears in the bt878-based card: FusionHDTV 5 Lite (I added preliminary analog support to v4l cvs last night -- audio broken, but great picture, can tune all channels, and closed captions work great, although sometimes the language changes to the wrong language by itself) > I hope I can get something ready later that day.

So why not starting with a known one. I think that you are correct. It just seems to me as if TUA6034 needs to be handled on its own, just as you suggest... If you need any information from me, please let me know. Thank you. -- Michael Krufky
