Fix simple bugs on a jommla website components

Hello I have a movies/videos website which is based on joomla. I need to fix some bugs in it. You have to be very strong in joomla and familier with components ! This is a small project but there will be a bigger one following if I see it been done ok. The bugs are : [login to view URL] Movies Section component - The script which is taking movies from other website does not take many movies that I think it should. [login to view URL] Movies Section component- The script which is taking movies insert more than one record for the same movie . [login to view URL] Movie Section component- The Script that is taking movies for other website stopped working and no movies are taken. [login to view URL] language - the drop down list don`t work,the page is not translated according to language. [login to view URL] jwplayer streamer stopped working,same for ustream player and about [login to view URL] - I don`t understand how to operate multiple channels.
