Dual BT878 based cards

[miriad]

Sorry if this is an old issue, I could not find anything on it when searching.

My setup is a 2.4Ghz P4HT 1GB ram with a PVR-160 (Roslyn), a Avermedia AverTV (BT 878 based software encoding), and an OLD ATI TV Wonder VE (Also BT878 based software encoding).

The Roslyn shows up and works (recently got the brightness issue, but thats a different story) no matter the configuration of the other cards.

If only one of the 878 based cards is installed (I've just been installing and uninstalling drivers to test this, not physically removing the card) SageTV sees and can use that card. Both of the cards work very well here (The TV Wonder, surprizingly, has as nice of video quality as my Roslyn does (before the brightness issue))

If I install the drivers for both 878 cards Sage does not see either card, just my Roslyn, and if I had either 878 setup as a video source, it is now gone.

Uninstalling the drivers for either card and restarting Sage allows Sage to see the other card.

Is there any reason running two 878 based cards would be a problem?

More importantly, is there a way to fix it?

SageTV 6.1.9

No idea. The cards are unsupported.

These cards both fall under the "Software encoding cards with WDM Drivers" on the system requirements page

Except for this. The word "Most"

Most other WDM capture devices should work with Version 5 or later but have not yet been tested. The above list will be updated as other cards are tested. If you have tested a specific card that is not listed, please report your findings to us at support@sagetv.com.

You need to report back that you haven't been able to get them to work together. Not all drivers support having 2 of the same chipset tuners in one machine.
So they're not unsupported if used singly but unsupported if using 2 in the same machine.
