I'm not sure what Mac eventually introduced, or whether or not it
would possibly have affected your card.
No... Mac was talking about ways to switch RF inputs on the
FusionHDTV3 Gold-Q model, which used a microtune tuner with two RF
inputs. My tuner only has one input, and it has always worked with
Mac's callback implementation. Kirk has used a similar method to
implement this in nxt200x.
Yep, that is very clear. I'm just throwing out ideas ... Recall that

I was just wondering if there was (a long shot) connection between your
analog going dead and this.....I was thinking along the lines of a bit
becoming "stuck" ... which reminds me, was there not discussion about
something being stuck, and requiring a switch into a Windows environment
to unstick the bit, early in the development of the Fusion drivers?
b) What analog demodulator is used in the Fusion 3s
(18ac:d800,18ac:d810,18ac:d820) ? What did Mac use? (he didn't
mention:
http://www.linuxtv.org/mailinglists/linux-dvb/2004/08-2004/msg00074.html)
Wow... Very interesting thread, although unrelated to this topic.
I hummed and hawed about whether or not to start a new topic ... but as
this particular discussion (dead analog in Fusion 3) was introduced in
this thread, I thought I would continue it here....Nonetheless, thank
you for adjusting the subject heading to more accurately reflect the topic.
Wow... Very interesting thread, although unrelated to this topic. In
that thread, Mac was discussing DVB API changes needed to support the
American standards.
Yes, I know what Mac was discussing. Perhaps I didn't articulate my
points to question b) very well. Anyways, what I was trying to convey was:
a) That was the first post Mac made regarding the Fusion 3, in
particular, its analog side, and he didn't mention what analog
demodulator it was using....In fact, I don't recall him ever mentioning
what IC is employed.
b) Discovering what analog demodulation IC is used might greatly aid in
the discovery of why the analog side of your card is no longer
functioning...and whether or not it can be restored (hopefully).
Anyhow,
18ac:d800 FusionHDTV3 Gold temic4042 + lgdt3302
18ac:d810 FusionHDTV3 Gold-Q temic4042 + lgdt3302
18ac:d820 FusionHDTV3 Gold-T thomson7611 + lgdt3302
Yes, I know all that (as you very well should know :-) ) , but it still
doesn't answer part (b) --> i.e. what's the analog demod.?
Please note: the 18ac:d800 subsystem id is not yet included in
cx88-cards.c, although card=17 will probably work. If somebody can
confirm it, then I would be happy to add it in.
Cool. As you already know, I picked this last part of the discussion
up on the DVB list. Perhaps Taylor or someone else will let us know.
