Diashow shows photo 50% size

When I'm using myRemote it works very nice
I'm from my beginning (2,5 years ago) struggling with the size of the photographs showed on the tv-screen
When i show one photo after the other, the photo fills the screen completely
When change to diashow-mode then the size of the photo's change to 50% (50% lenght and 50% height);
so there is ABSOLUTE NO FUN showing with the diashow mode!!

Long ago i had mailed over this problem (to jointspace i believe), but never received a reaction

Have other user's the same problem?? can it be resolved???

(My tv is Philips LCD-37pfl9604h , i use my app and from iopd or ipad 2)

thanks for any resolution
