Hi, I used to have that product but I changed it to 4 pcs of Ezcap 108. That thing that you have just won't record simultaneously. It also lags when the Multi-viewer is used to view multiple videos.
I have the same problem with my newly replaced Ezcap 108. I bought 4 pcs and only 2 works at the same time. The other 2 causes my Windows 7 to have the Blue Screen of Death. I also can't install the drivers since Windows 7 auto-detect the drivers needed. And the Blue Screen of Death appears when I try to uninstall the driver for the "Composite USB device".
If you have found the solution, please keep in touch

Thanks
