I'm in favor of the patch if it is behind a "--rtsp-ncube" setting (i  
believe this is nCube RTSP dialect).
And I agree with Ross partly on this YES it is retarded. But if  
people wanna use it, they should be able to in VLC.
The amino boxes constitute a large part of our users.

I have to say though that i'm increasingly more inclined to let VLC  
print Warnings that inform users they are using non-standard  
protocols/equipment, and that they should inform the developers of  
this stuff.
