You should search the forums, as this has been asked and answered over and over again.
Hint: It's in one of the files that FP reads for settings information.
I have just installed frodoplayer and it looks great but one thing is the resolution is set wrong and i cant find where to change it. Currently it is set as 800x480 which only covers half the screen,my resolution is set at 800x600 which is a bit annoying. I can see under menu-settings1-skin there is the resolution displayed but i seem unable to change it in any way. help please.
