Video File Formats for Media Player?

[gabor]

My own video in .avi is reluctant to connect/download on visitor's screen.
The file resides in my public_html directory.
Should I convert to .wmv?

If someone is bold enough, plese go to site: www.gabor-music.com

Path:home/next/music/albums/Happysillysexy. (In-text hyperlink).
There are a number of version in there.

They all play on my own computer.

Thanx
