The version of dvbstream bundled in debian etch/lenny can only handle up to 4 dvb devices. For stability in my mythtv system, I have created higher artificial links/devices via udev, such as 5,6,7.
The attached patch allows dvbstream to access up to 8 devices, to allow access to the linked devices.
