something like vga2scart.eu.org sounds good. Though our project
is not limited to vga2scart. In the meantime I successfully use a
modified version of the vga-sync-fields patch on DVI/HDMI interface 
also. Providing me high quality 576i over DVI/HDMI on intel i9xx machines 
with SDVO ports.
Originating from SDTV our project could be important for HDTV also.

I wonder why nobody else joins our discussion.

Just to clarify:
My major goal was to prove that graphics cards can provide the same
picture quality as FF-cards do. But with wider flexibility at fractional 
cost of a FF-card among many other advantages. And without the need of 
expensive and time consuming hardware mods like full-TS mod, AV-board,
J2 mod etc. 

We now have a working sample installation for a budget system with
FRC based on easy-vdr [4] which has been successfully setup by various people.
Reaching this stage I consider my 'mission' completed.

You can setup a repos with current source found in vga-sync-fields
package at anytime. Everybody is invited to test and contribute. I don't 
consider it as 'my' project. I just will contribute the initial idea behind
frame rate control and a sample implementation for it.

And of course I will continue to develop as time permits.

ok, I wouldn't bother much to log in. It depends on what the majority of
possible contributers would prefer.

no.

I don't know. But I think an english doc should be enough.

At least they have a wiki. The German VDR wiki [1] refers to [2]
when you select the english language button.

right.

sorry, I can't tell

unfortunately it's not an option ATM

'gitorious.org' appears ok for me. As I worked alone yet on this project
I did not use any source code control system until now.

As said, I don't consider it as my project. Everybody is invited to 
improve the project status. There are left many ideas and features still 
not implemented.  
I already wrote a to-do list with issues of lesser priority. But features 
that would improve things a lot. 

- like writing a tool similar to powerstrip. Which lets you adjust overscan
and other parameters in real time by pressing cursor keys. or

- derive xine's masterclock from graphics card frame rate. This would 
provide almost instant sync after a channel switch. The idea for this
was published by 'durchflieger' [3]

There are still left many things to do. As often in life it's not a matter
of ideas but a matter of time:)
