I guess this scenario is a little too "special" to justify extra Ca values.

However, you should be able to achieve what you want by adding the following two
lines to dvbapi.c:

 int cDvbApi::ProvidesCa(int Ca)
 {
+  if (this == PrimaryDvbApi)
+     return 0; // in this system the primary card can't receive anything
   if (Ca == CardIndex() + 1)
      return 1; // exactly _this_ card was requested
   if (Ca && Ca <= MAXDVBAPI)
      return 0; // a specific card was requested, but not _this_ one

Haven't tested this, but I guess it should work as expected.
