Is there software that can automatically convert the files?A: Examples and instructions for using Apple Script to manage the process with QuickTime Pro are available on Apple's developer Web site.

I was thinking about running an Ethernet cable from a hub where the 2-Wire is located to the upstairs location and put another wireless router at that point. Will this work, or do you have another suggestion?A: I didn't find anything on the 2-Wire Web site to indicate that your 1000SW had external antenna jacks for Wi-Fi component of the router. If you do have antenna jacks on the back of the unit, see if you can find external antennas for the unit either from the manufacturer or from a third party. This might be the easiest way to increase the coverage area of your existing system short of adding another access point.To read Ron's response in its entirety, please click here.
