Based on that error message, I checked my settings in Skype to make sure the speakers, microphone and camera are all set to the correct devices (which they are). I have read the boards on here that talk about how to use your MJ dongle with Skype and a cordless phone, but that appears to be if you want to use Skype for your regular phone as well.
Is there a way to use both MJ as my regular home phone and still Skype with video?
Can't we all just get along?
