That passage in Wikipedia merely describes the format that the phone uses to save/play videos.
As long as the video you are watching on your phone is in that format, you will be able to see it. If it isn't, you will get the "Error while opening file" message.
If you are asking how to view your phone's files at home, download "VLC".
It will play just about any file that is generated by any media device including mobile phones.
