I've recently set up a MythTV frontend using Minimyth on a board with a CN700 and a VT1622A. I'm using TV out via S-Video to a CRT TV with Scart input. I initially set up mode 720x576Noscale, and was pleased to find the TV image fitted to the TV screen exactly, but there were a few strange things that started to make me think that the image was being scaled:
1) The OSD images had to be adjusted to about 650x550, for it to also fit the TV screen. 2) The TV image showed various artifacts that could be exaplain by scaling (jagged diagonal edges, rippling during pans, a general softness of focus). When I first looked at the X screen via VNC I found TV was being scaled. The X screen was 720x576, but the decoded TV image was being mapped onto a 650x550 subarea, and this area was somehow mapping exactly onto the TV screen. I've just swapped to using the mode 720x576Over. I get a much better quality image, and now the TV image extends off the edge of my TV screen by the same amount as the OSD. If I look via VNC, I can see the TV image mapping directly to the full 720x576 area of the X screen. Anyone know what's going on here? Also, anyone know how I should adjust the mode to fit correctly to the TV. I have no real experience of adjusting X. Is there a tool that allows on-the-fly adjustment of mode variables?
