Adding DRO to new tab in axis

I have a Live Video tab that I created in AXIS and I need to add a DRO to the tab. (overlayed onto the video)

I saw where to do this a few years ago but not I cannot find it anywhere.

can someone point me in the right direction please?

Is the live video tab a GladeVCP entity? If it is then you should be able to edit in Glade to add a hal_dro widget.

Thanks Andy

I just added to the INI file

[DISPLAY]
EMBED_TAB_NAME = Video
EMBED_TAB_COMMAND = mplayer -wid {XID} tv://0

whats my best (easiest) option?
