Are you saying that NVIDIA hardware and software drivers are CEC 
compatible, and that all the manufacturers have missed the commercial 
opportunity to add value, and charge more for a niche market?

I doubt that is the case, noting for example that Sparkle and not many 
more took the opportunity to make PCI VDPAU cards, when the others 
largely missed that opportunity etc.  Pennies did not seem relevant when 
looking at the price premiums for these cards.

It seems much more likely to me that, in the least, NVIDIA did not 
promote the opportunity to its downstream manufacturers, who also did 
not foresee the market opportunity.

NVIDIA has had customer "pull" for implementation of this technology, 
searching their forums will prove this.  They can't say there was no 
evidence of demand.

While, CEC to me is a good concept, it seems to require an HDMI chain. 
(Although CEC commands may also be routable over Ethernet?)

An IP solution seems a better way to go as it is even more widespread 
than HDMI, and I am delighted with the prospect of mythmobile that is 
coming along, although I've not had the time to install and trial it 
yet.  Either way there will be demand for Digital interface to older 
hardware which does not have HDMI or IP connectivity or controllability.

Having said all that Mark Kendalls enthusiasm and feedback is to me 
significant, I do not wish to be mis-understood as undermining that, I 
most definitely am not.  A particularly good thing about mythtv is its 
widespread flexibility to do much for many people.
