I also have an ADS capture, mine is pci and uses s-video or composit. What do you see in Nero ?
click start
then run
type sysdm.cpl
hit enter
then click hardware
then click devices
see if you see any errors. like a red X or !
1. the device could be broken (ADS or CAMERA)
2 you may not be receiving video from the camera
3. or the drivers need to be uninstalled and the reinstalled for the capture device
Did you try contacting ADSs tech support or seeing if they have a forum.?
