I purchased an SD-1 with the optional video interface. I haven't been able to get the video out to work. It's not the TV since the TV worked with my X1. I think the problem is that I haven't found a way to select the video output (PAL, NTSC, Monitor etc.)The manual says to press the F8 video function repeatedly. This doesn't work. In fact, I don't even see the video output options. I first select "song play" to put the keyboard in video mode and then F7 "Video" and then F8.

Can anyone help with this?
