Images are being freed from buffer when there is lack of memory and then loaded again.

@vijaykumar - you can't "increase buffer memory".

Instead "lighten up" on your images. No "heavy" images!

It's quite common for people to abusive with image file sizes, not accounting for how low the TV resolution is - the 10ft experience is entirely different from PC monitor.

Unless line-art, use JPGs with higher compression and possibly undersized - but never oversized
