Thanks pe1chl for your response.
After some heavier digging it seems like this is just something the driver is missing .. and will never be implemented judging by the non-response to this post in 2004: http://www.nvnews.net/vbulletin/show...ight=component
I have noticed that I get 50Hz refresh in HD576p. There must be a way to specify a 50Hz mode in 1080i .. I know 1920x1080_50 method doesnt work and that all the modes listed in the modepool dont actually show the refresh, but there must be a way?? How come the 720x576 mode added to the pool in HD576p is 50Hz but nothing else is?
I know modelines dont work, but is there some other way to gain some control over what is put in the modepool for TVout?
