Question 1:
How many Markus Rechberger people of Austrian origin does it take to milk a 
cow? 

The answer is: FIVE!

One sitting down to keep the nipples in the line, the other four to lift the 
cow up and down.

Question 2: How many attempts does it take to teach the Markus Rechberger 
people of this world what an API standard is?

The answer is: ENDLESS!

The reason is: They simply miss the intellectual abstraction layer to be able 
to spell what an API at least could be.

Question 3: How many attempts does it take to teach the Markus Rechberger 
people what a compromise means?

The answer is: ENDLESS!

The reason is: They simply miss the intellectual abstraction layer to be able 
to spell what a compromise at least could be.

Question 4: How many attempts does it take for the Markus Rechberger people to 
force intelligent people like Greg Kroah-Hartmann to host their incomplete 
nonsense in a separate repository?

The answer is: ONE!

The reason is: People like Greg Kroah-Hartmann are not dumb at all, but people 
like Mauro Carvalho Chehab obviously are as a matter of fact.

Question 5: How many attempts does it take for the Michael Krufky people to
understand that their "code duplication" proposal is nothing but an ugly 
decision at all?

The answer is: ENDLESS!

The reason is: They simply miss the intellectual abstraction layer to be able 
to spell what a compromise or a distinction of exception cases at least could 
be. They also cannot even spell what an API is. Thus they declare the usage 
of dvb-pll.c as a dictated standard to be used for all bt8xx cards, knowing 
very well that simply and only ONE driver (i. e. the one that they personally 
developed) really needs it (i. e. the one with the lgdt330x frontend). And 
thus the stupid user folks (plus the more stupid Markus Rechberger folks and 
the pseudo-authorities like Mauro Carvalho Chehab follow them, like every 
flesh-and-blood stupid nut who never learnt to use his own brain without 
external leadership would follow them).

P. S.: Every kind of community in which the dumb stupid nuts gain power over 
the more intelligent people really makes me vomit, as the only effect of it 
ever was, is and will be that the real capable people will run away, leaving 
the things to be done to some utmost stupid, incapable, rubbish two-legged 
asshole who himself does not and will never establish anything functionable.

The first and utmost urgent need to be fulfilled is to establish a leading DVB 
maintainer being and living beside of a real neutral v4l maintainer without 
utmost primitive drives as a consequence of missing DVB knowledge.
If Mauro Carvalho Chehab cannot and does not conform to that it is an utmost 
necessity to substitute him and replace him by a real capable person as quick 
and as urgent as possible.

P. S.: In the past there was some Gerd Knorr who never in his life claimed to 
be the "Big Boss" like stupid motherfuckin' dumb Mauro Carvalho Chehab.

Plus: In the past there was a common "melting pot" like the Convergence 
company at Colgne, Germany, consisting of Ralph and Marcus Metzler, Michael 
Hunold, Johannes Stezenbach and others. They knew each other, they smelt each 
other, they worked with each other.

NOW: There is a repository as a sum of individuals who cannot work with each 
other, who do not know each other, and, above all, are dictated and ruled by 
a "I-Would-Like-To-Be-Maintainer" from Brazil who is doing nothing but 
playing bad politics, and who himself is utmost limited to some mediocre 
v4l-knowledge.

No future for linuxtv.org if things go on like that, people!
There need to be urgently some personal changes of the utmost radical kind!

And human crap who takes first position to be shut down and go away is of 
course Markus Rechberger, who else??
