[AG-TECH] hauppauge video problems

[Michael Miller]

Just to add to what Ti said:

My experience has been that, depending on the driver, you can select the 
WDM device in the configuration of multiple VideoProducers.  When vic 
starts up, one of the WDM cameras is automatically selected for the first 
VideoProducer.  Then you are given a series of dialogs to choose a camera 
for each remaining VideoProducer.  Again, whether you get to choose another 
camera will depend on how the driver enumerates the cameras.  The QuickCam 
Pro 4000 does show you multiple cameras, but it gives them all the same 
name.  So, it can be confusing when trying to choose a camera for the 
subsequent VideoProducers.  If you have two different cameras, the WDM 
drivers will assign names as appropriate and it's much easier to decide 
which camera to choose.  I have an iBot firewire camera and a QuickCam Pro 
4000 so I can see which camera has become the default after the last 
session.  If you have two of the same camera and the driver doesn't assign 
each a unique name, that's when you run into trouble.
