Thanks for the info guys. Since the firmware is closed source I'll try to give Ralph's suggestion a shot and see what happens. It doesn't look like it would be too hard to add support for creating a VIDEOHSIZE window in the osd code. I'll let you know what happens but I have to wait till I get home from work :-)
