Yes, the HTPC is connected via composite to a PAL-I TV-set and RF modulator 
(using RCA Y splitters).

The problem is that Freevo is using CONF.geometry, while PyOSD is using the X 
display's size. As a result, pyosd.POS_BOT is not always where one would 
expect to find it. A possible solution would be to use:

self.osd.set_pos(pyosd.POS_TOP)
self.osd.set_offset(config.CONF.height - 100)

Best regards.
