Why isn't my LG optimus giving me the options to choose a video format?

[AC Question]

I am using LG optimus, Issue with Video format promt

before when I play any video I used to get a prompt to choose video format with 2 options like always or once. By mistake I choose always but dont know what format its playing I want to change it back old style and get the prompt again,

After choosing this format , video will not rotate and play in middle of the screen and its very small.

Can any one please help me changing the settings.

Thanks,
Divya
