More progress. Help from any forum member would be great
Using 'Resource hacker' (app for reading and editing DLL files), I have found the dialog box that opens when in yawcam, I follow- Settings, Device(SMI Grabber Device), Device properties. It is located in .../System32/kswdmcap.ax which is one of the many files listed when I go into Control panel, System, Hardware, Device manager, Sound video and game controlers, SMI Grabber Device. Which according the driver details comes from Microsoft.
kswdmcap.ax, Dialog, 103 contains-

103 DIALOGEX 0, 0, 240, 130
STYLE WS_CHILD
CAPTION ""

}
------------------------------
This is the content of the dialog box that is used to select the Video standard. The line 'CONTROL "", 1060, COMBOBOX, ....' is the combobox where the the selection is made. (the combobox is populated from one of the other listed DLLs, but cannot find again at this moment)
When bringing this dialogbox up via yawcam, it is superimposed on another diagog box with the 'OK, Cancel Apply' buttons (which I must assume as that outer dialogbox is not found in the driver files for this device, is a generic dialog box from elsewhere).
Now I am stuck, and would appreciate help form any forum member with knowledge of driver files. After setting the Video format (via yawcam bringing up the dialogbox), the change is not saved in the file kswdmcap.ax (but already knew that as the setting is lost when the pc reboots).
Anybody got any ideas?
Importance? Using yawcam is for the purpose of looking at cam/s from another location. But if the cam (in this case, PAL RCA video coming in via the £6 EasyCap USB adaptor) cannot be accessed without someone being present to re set the video format setting, it defeates the object
