Video call when Skype doesnt work...

Skype is great for calling, but also has a good video call function. However sometimes it doesnt work. Especially between a PC and Mac. So one needs alternatives. Heres an overview over 10 different video conference applications: 10 Skype alternatives I tried SightSpeed, but never got it to work apart from the chat function which was like a poor Messenger.

Apparently in January Microsoft will release a Beta of Windows Live Messenger for Mac that finally supports video too. Lets keep our fingers crossed and hope it works well.
