problem Capturing video in SLI...

[SAOD]

First of all forgiveness on my English...

i have 7800GT X2 sli
I try to capture a video, but without success, I thought maybe to cancel Sli,
You know like the problem to clone and.. soo, Then I did so and not helped a thing, everything that I did, did not help . only in the end after I took out one card really in the physical way, I succeeded capture!

WTF??

I will be happy to the help, thank you very much in advance
