This didn't make it over to the linux-dvb mailing list, so I can only 
assume that Mauro isn't subscribed using that email address.  Anyhow, 
this announcement applies to everybody, so please read:

...and I would like to add, that users can get an idea of how this 
merged tree will build by using v4l-kernel's "make merge-trees" command.

As an intermediate step, I have added dvb-core and all of the other 
dvb-kernel modules into the v4l/dvb merged build environment.

'make merge-trees && make' will now build every module from v4l-kernel 
AND dvb-kernel.

cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/video4linux login
cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/video4linux co v4l-kernel

cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv login
cvs -z3 -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv co -P dvb-kernel

cd v4l-kernel

make merge-trees && make
make install

...After we're done with the merge, the 'make merge-trees' command will no longer be necessary...
The new, merged cvs tree will behave similar to that of the merged v4l/dvb build environment.

Cheers,

Michael Krufky
