HEllo
I just wanted to know you computer to know if thats the problem. becaause i dont know if you know what skype is but i has problem with for examples dell inspirons 1150. so ya never mind.
well If i were you i would download 3.68. it has the most options and is must stable.
http://s1mp3.org/en/downloads_tools.php click on the 3.68. ok and what size screen do you have. Because if yours is 1.5 inch then it should be 128 * 94. something like that and the 3.68 has that option and bigger. remember middle quality and middle resolution and try another codec.
bye
