Can someone please explain capture cards numbering

[linfor]

I have two Hauppauge cards - PVR150MCe currently installed and PVR150 which I am adding.
No matter what I do I cannot seem to get both to work at the same time. the 150MCE is set as capture source #1 - I thought since they use the same driver I could set the PVR150 as capture source #1 also - that did not work, neither did setting it as number 2.
Any help appreciated.

One will be device #1, one will be device #2. Which is which? I dont know.

The original device that was #1 may now be #2.

Is there a way I can check? I do not really care which is which except that it will only record from one at a time and I need it to record from both.

I sorted out my mess (3 cards, 5 tuners), by removing all from gbpvr.
I then did a reinstall, choosing the repair option, then installed the tuners, one at a time.
This resets all the info for gbpvr somehow, and now they all work.
Seems (for me) to be the only way.
If I simply try and add a tuner to the existing setup, it never works.

Looks like the only combination you haven't tried is to set the MCE to #2 and the 150 to #1.

I originally just had a 350 (#1 obviously). When I added my 500, the two tuners on the 500 had to be set to #1 & #2 and my 350 as #3 to get things to work.
