i have both an iMac G5 (isight) and a Macbook Core 2 Duo. both machines run skype video conferencing EXTREMELY slow and choppy, almost to the point to where nothing is understood. i have used my macbook at school with skype with no problems with the same (and only) person on the other end of the line. i have a Belkin pre-n router, which i believe is the cause of the problem. I have tried forwarding the ports of the specified port, (anyone know what the default port for skype is? i changed it) just TCP, then both TCP and UDP, then just UDP, to NO AVAIL. please help!
