Snippet from your attached AGServiceManager log file:
08/17/04 11:17:43 1075394784 Platform Config.py:670 INFO /proc/video/dev
does not exist; no video devices detected
It's a bug with AGTk 2.2, /proc/video/dev does not exist, which is typically
because kernel 2.6/V4L2 is being used.
The fix is to use AGTk 2.3 Beta1 or modify the following file:

The modification involves replacing the GetResources function with the
version from CVS's Config.py:
Then add the following import lines somewhere in the top of Config.py:
CVS (and 2.3 Beta1) also has version's of VideoProducerService.py and
VideoService.py which fixes issues with S-Video port selection.
