Build BDA Graph - Enum tuners

I am building a DVB application. To create the direct show graph I enumerate
KSCATEGORY_BDA_NETWORK_TUNER and choose the one I want depending on its
index in the enumeration. Then I create the reciever component by enumerate
with KSCATEGORY_BDA_RECEIVER_COMPONENT and tries to connect them to the
tuner device. If the filters connect I assume that they belong together.

But in my test computer I have a Technotrend budget DVB-T card and a
FireDTV-T reciever. The FireDTV is the first in the enumeration. If I try to
create a graph with the Technotrend device the tuner device is ok but when I
enumerate the recievers I will create the FireDTV one first since it is the
first in the list, and it connects with the Technotrend tuner without error!
Naturally the graph wont work with this configuration.

Am I doing this the wrong way or is there a bug in some of the filters? Can
I assume that the filters that belongs together has the same index in the
enumerations of tuner and reciever filters and do it that way instead?

Thanks
Anders
