[vdr] cOsd tArea explanation

["Maynard Cedric" <maynard.cedric@wanadoo.fr>]

Hi all,

Well, I'm fighting with those tArea and trying to understand why :

tArea Area = { 228, 50, 623, 99,2};
osd->SetAreas(&Area,1);

just work fine and why

tArea Area = { 228, 50, 623, 99,1};
osd->SetAreas(&Area,1);
Won't..

The main difference between the two is the number of color (right? 4 for the
first, only 2 for the second)
So why with less color this area won't show?? (and the CanHandleAreas()
return false obviously)...

If someone can explain me where I went wrong, I'll be thanksfull!!
