Mobile AVC software to watch movie online for free

have you ever need to move the movies you have from the computer into the portable device like mobile phones, PDA and PSP or even MP4? off course you can move the file directly but do you know what will happen? yes, the file wasn't play able in the devices. in that case you will need the program which i have already used for converting the file. converting the file is what you have to do before moving the file into the devices. I was so confuse at the first but then it was a piece of cake for me after i read the manual. the GUI was really helpful.
