I recently upgraded to Leopard on my ibook G4. I'm running Skype 2.0.0.6 - and multiple times in the past week I've attempted skype calls where the other person's audio comes through at what sounds like 2x normal speed...pure chipmunk style. They seem to be able to hear me okay.

There is also a regular problem with my video image freezing about 20 seconds into these calls. I have no idea if this is related or not.

This has happened with people who have macs and people with PCs.

Any thoughts as to why this is happening and what I can do about it?
