Here is the proper setup for the AVerMedia M780 Combo PCIe

[bogyver]

I just checked and it works on my system. it proved to be a bit taxing on the system because i had to get 2 recordings going and then start up live tv. Right now i am testing recording with all 3 tuners to see if i run into any problems but im not seeing any errors and all status info says that i'm recording on both of the tuners on the m780

Well i can confirm that my system will record on both digital and analog tuners at the same time, if i can help you try and figure out whats differnt between yours and my setups just let me know

Ok, bogyver. In setup, I have both devices as #1. One time, I had it recording on both tuners at once but now cannot reproduce it.

Thats the way I have it setup on my system, Just to confirm you are able to use both the analog and digital tuners seperatly?
If so I think your best bet would to be uninstall and reninstall gbpvr and possible the drivers for the M780 as well
Also I am using an older version of gbpvr version 0.99.12, I havent had the time to the upgrade with all thats been going at where I work (I'm a IT support guy at the school i go to, we moved our office and server room to a new location and some the old timers have a lot of junk to be moved, not to mention the servers. It's actualy kinda funny my major is chemistry and I ended up working at a IT job my last year at school)

If there is any way i can help you just let me know

Yes, I can view and record them separately. I shall try uninstall and reinstall.

I uninstall and reinstall both gbpvr 1.08 and m780 drivers but no go with both tuners at once. In Device Manager, I show under Sound.. only Tuner, Bridge and Video Capture for AverMedia. I would think it should show two tuners like my Hauppauge 500.

Reproduce the problem, then zip and attach the logs and I'll take a look.
