Media player for LG Optimus One

The stock media player in Android is just ok. It will not play all video files. If the resolution of the avi file is higher (resolution more than 640x360), it will give an error message "resolution not supported".

However, you can freely download Moboplayer. This is the best player I have tested. They say that it can technically play any file played by VLC media player, since they use the same codecs (FFDshow). Anyways, Moboplayer was able to play the files rejected by stock player. There was no "resolution not supported" messages anymore.

Note: Make sure your video file does not have AC3 audio. mp3 and AAC audio work fine.
