In this fix: Resolved issue with Windows PlayTo not playing MP4, 3GP and AACADTS files
Yes, I can PlayTo MP4 files now, but there is strange behavior with playTo images.
First image is displayed correctly. Second image flashes briefly and black screen.
Third image is displayed correctly. Fourth again briefly and so on only over one image is displayed correctly.
It is so with both Windows 7 (Media Player) and Windows Phone (Lumia 620).
If I send images from Windows phone to windows 7 all images are displayed correctly.
This behavior was also with previous firmware.
