white screen in icam Mac OSX (with 2 tv tuners)

[deejc]

hi There,
i have recently got 2 tv tuners hooked up to my MacBook, and since this time icam has stopped working and just shows a blank white screen whenever i start it up.
i have a pinnacle 72e and an eyetv dtt connected to a usb2 hub (4 port) also on that hub is an elgato turbo.264 and my external sound card (native instruments audio kontrol 1), when they are all plugged in icam doesnt work, when only the 2 tuners are in it works until one of the tuners displays a tv program then it stops again.
is this normal ?

It sounds like you have lots of inputs that may not be able to run at the same time ... We don't have experience with that kind of setup, so I can't really say for sure if it is "normal" or not.
