AverMedia HD DVR - Frame drops in live playback

[Anonanon]

I'm not even recording anything, I'm just simply watching the live output so I can try playing console games on my desktop. This used to work flawlessly some time ago. It was not until recently that after X minutes, the live playback gradually loses frames per second until it gets extremely sluggish.

I suspected it was a driver problem. I tried both the new media center, called media center 3D, as well as the old one. Same with drivers, tried new and old. All of them still drop frames after some time. I also tried moving the card to another PCI-E slot. My next idea was perhaps the card not getting enough power (I did lower the voltage for winter), I increased the motherboard voltage from 1.345v to 1.360v and I'm still getting drops, except not as bad. I idle in the main dashboard of the PS3 where it's supposed to be a silky smooth 60 fps, it looks choppy after 15 minutes or so. The weird thing is, it returns to 60 fps silky smooth if I close and reopen the application. My Windows 7 is free of bloatware, obnoxious antivirus, running less than 40 processes.

Fixed. The problem was Nvidia 295.51 beta drivers conflicting. Rolled back to 290.53 and everything was good.

Just wanted to say THANK YOU SO MUCH for finding the solution to this problem, it was happening to me too with the Game Capture HD and I was about ready to call my card defective and ask for a new one... I was like "it's an i7-2600k processor, why can this not handle 720p playback?" Guess I'll wait until NVidia fixes their drivers.

Also, note to everyone else who still has this problem after rolling back to the 290.53 drivers: remember to shut down your computer, physically remove the capture card from your motherboard, re-install it, and boot up the computer. NVidia's GUI won't prompt you to restart after installing the drivers so some folks might miss this step.

Just a heads up, Nvidia just released official 295.73 drivers, non-beta. Massive performance gain in Skyrim plus the ability to natively cap your fps.
