There is no way to tell what the dialog settings are current set to using the Quicktime APIs and there is no standard way that driver authors implement the dialogs so it is difficult to figure out what is going wrong. It is possible that whenever the dialog is called the settings on the USB cam are reset or at least appear to reset. I had this happen with some terrible industrial cameras before I ditched them for DV.
You can use a message like [device 0, input 0, dimen 640 480( to set the device and then the dimensions. Since both the iSIght and webcam are USB devices then the input number might have to change instead of the device. The order they appear in the dialog Source list will give some idea what order they are in as will the info printed to the Pd console.
