Steve can you comment the differences between s2 and s2-mfe trees and 
whether those are planned to be compined in near future?

To my understanding the only difference between s2 and s2-mfe branches 
is the support for hvr-4000 style of devices. So:

- s2:
 	--> would support only 1 frontend for 1 card at a time. Therefore 
one would need to select during the driver loading time whether to want to use 
hvr-4000 in DVB-S/S2 mode or in DVB-T mode.

So in dev-tree following are available:

[root at tinka vdr-1.7.0]# ls -la /dev/dvb/adapter0/
total 0
drwxr-xr-x  2 root   root     120 2008-10-05 10:56 ./
drwxr-xr-x  4 root   root      80 2008-10-05 10:56 ../

- s2-mfe:
 	--> can create multiple fronends for single card eventhoughg only 
one of those can in reality to be used simultaneously. Thus one 
does not need to select between DVB-S/S2 mode and DVB-T mode 
during the driver load time. So following nodes are available:

[root at tinka vdr-1.7.0]# ls -la /dev/dvb/adapter0/
total 0
drwxr-xr-x  2 root   root      200 2008-10-05 10:56 ./
drwxr-xr-x  4 root   root       80 2008-10-05 10:56 ../
