There is no officially supported solution available for using VideoSync with a Power Macintosh AV system. But, there is a workaround that you may want to use.
You could could use a third-party sense code adapter, such as the MacLiberty Adapter from Enhance Cable Technology. This adapter has an adjustable dial allowing it to send the Macintosh video card the correct sense codes for a variety of different screen configurations.
By selecting the appropriate setting for VGA or SVGA, a Power Macintosh AV system makes two video modes available, which will display at a 60 Hz scan rate. These video modes are the VGA resolution of 640x480, and the SVGA (also sometimes called VESA) resolution of 1024x768. These modes can be selected by clicking on the "Options" button in the Monitors control panel.
Because these video modes use a 60 Hz scan rate, these resolutions are suitable for filming and video taping. This enables you to use a sense code adapter as an alternaltive to the VideoSync software. Be aware that 60 Hz is definitely not suited for filming and that 60 Hz will create a visible, though slight, roll to the picture.
The Tech Info Library article titled "Locating Vendor Information" can help you search for a particular vendor's address and phone number.
