[AG-TECH] Re: Winnov Videum Quattro

I'm new to AG development and I could use a hand with a fairly basic question.

Today I dug some more and found the VideoProducerService.py file in
...\Application Data\AccessGrid\local_services\.  Under MapWinDevice,
the software iterates through the videum drivers and sets registry
keys for Source, Height, and Width.

keyStr = r"Software\Winnov\Videum\vic.exe%d" % (devnum,)
                key = _winreg.CreateKey(_winreg.HKEY_CURRENT_USER,

It seems that this is were the source keys get set to 0, 1, 2, 3 and
where I would like to try setting them to something else.  Can I just
edit this python file here and the changes will be implemented when I
run again?  Do I need to repackage a VideoProducerService zip file and
install it with agpm?

I have tried editing the file in place and it seems that any change I
make causes the service to become unreachable.  Even just adding in a
statement to print to the log file.

If anyone has a pointer on this, I would appreciate it.  I'm appending
an excerpt from the VenueClient log to show the exception that I am
