Aviplayer plays avi,mov,mpeg,mp4,mp3,3gp,wav formatted files. You can simply run Aviplayer on phone without connecting to internet. One click and Aviplayer plays whatever you want. If you have iVoiceBrowser, you can also play files from internet on Aviplayer. Aviplayer plays avi from the root of the SD card. If the avi file is going to be played for the first time, Aviplayer converts the file to the right avi format for the player. This process takes a minute then you have a new playable avi.
