Answer:
According to the payoff matrix in the question:
If Movietonia chooses to price high then Videotech will prefer to price low as 15>11 and if Movietonia chooses to price low even then Videotech will prefer to price low as 8>2.
Thus Videotech has a dominant strategy- of pricing low.
------------------------------------------------------------------------------------------------------------
If Videotech prices high, then Movietonia prefers to price low as 15>:11 and if Videotech prices low even then .Movietonia prefers low pricing as 8>2.
Thus Movietonia has a dominant strategy of pricing low.

In case both do no collude. both will have pricing low as a dominant strategy. Both will and up choosing a low price.

The above situation is an example of prisoner's dilemma because if both of them cooperate and price high they end up earning higher payoffs than without cooperating.
