Your Adsense Ads are not very well placed and also you are not feeding them with much textual content so they won't be targeted.
For example on this page look at the text on the page:
http://balaga.net/content/view/441/215/
Google has very little to go on - for me it served a diet pills ad. Give it some good content to go on by adding a description to each video.
Try Switching off image ads as they usually don't perform well.
-------------
In general you will find this site like this very hard to monetize because it is offering free stuff - people will only come in search for free stuff and will not be interested in buying anything - therefore your traffic is low quality so advertisers will pay less - including Google.
Consider adding movie reviews, video software reviews etc. to your site for new movies to BUY - link to the movies using affiliate links. By having products or product related topics on your site you will get higher paying ads.
===========
Also consider using banner networks like Burst Media that pay on a CPM rate.
Also consider using CPA networks like CPAEmpire that pay for when you send a user that gives their email address to receive a free product - e.g a free ipod.
