Yes, but most likely Chris's driver for the non-lite Fusion DVB-T would be
worth following too - assuming that the board would be wired up similarly
(GPIO enable lines and all that).

I was thinking about adding (Mac) support for it but it hasn't bubbled to
the top of my list yet...

I have some programming info for this tuner - it should be enough to make
it go (IF + pll step size + band control words). Most likely others on
this list who have been in contact with DVICO have similar info. If you
are serious about writing this driver then contact me off-list and I'll
pass it on (with DVICO's blessing).

Yes I've been wondering about that too. I guess we'll find out for sure in
a day or so :)

{P^/

btw I've added support on the Mac for the ATSC part of the FusionHDTV 3
Gold now ... I think this must be the first time there's been a Mac 'DVB'
driver before a linux one :D </smug> :)
