I'm totally guessing as I have not the code under my eyes, but it can be an issue related to Garbage Collector. When my applications have some performance issues, I use GC.Collect(). It rarely works, but you can try to do it and see what happens. Actually I have not got a clue about the problem... you may try to call the method AFTER you have loaded a video, but there are really few probabilities for it to work. You may try to avoid using so many mediaelements or so many videos... I really hope this helps and is not useless... Unfortunately , performance issue s related to someone else's code are not so easy to solve... you may also try to use DirectX to play your videos. They might be more controllable.

Hi Rakesh,

Same problem I faced also before 6 months. For this first thing is that use GC.collect() in all the methods which will clear the memory.
Most important thing is that Do not play, pause or do any thing from XAML, means by its default controls.Please do all the things from code itself. Check it again and let me know that is there any changes in performance.

Thanks
