In my MC, even +30% brings them somewhat lower than the center, and 5 to 10 is a small step. So I guess it has to do with some of your settings. As I remember you use ROHQ, so first check with Red October Standard. Make sure you use a proper resolution. It might also be that you crop black bars or stretch (right click > Window > ). If one of these does it, change to ROHQ to check again. If it persists, then you've probably changed something in the HQ settings of RO that supersedes the standard settings of MC.
Gee Yannis you were so right thank you very very much!
I had a setting on madvr that you would think was correct, but it doesn't behave correctly!
In zoom control I had ticked move subtitles into the bottom of the screen window, this was never correct, it was moving them in huge jumps when I was selection 5%, 10% etc etc..
Ive now set it at "move subtitles into the active video area" in madvr, its now moving nicely in small steps. Set at NO SHIFT in JR its all now perfect, thank you again, Ive wasted so much time trying to sort this problem!
Tell me, will I have to now go back and reset all the films with subtitles I had originally moved?
When you make a change on one film does it always remember that change?
