I'm using MX player on a sony bravia xbr55x700d on nougat. It seemed like the current position is sticking to the last place the player hud was active. I'm getting the same jump to start everyone is mentioning when I attempt to seek, but ONLY if don't pop up the menus first. If I do, then I can sell from my current position normally. Every time I try to seek, it goes to the last position that occurred due to a menu interaction. For some reason, the player's tracking is stuck wherever the last place the menu was accessed was.
I can scroll just fine as long as I remember to bring up the menu first. I hope this helps narrow down what code to investigate.
