Browser incompatibility is a term used mostly when you have a portable device with internet capabilities, such as cell phones and Black Berries, that are having trouble accessing a web page; usually because it was created with regular HTML, not xhtml.
The only real difference between XHTML and html is XHTML’s designed for small portable devices and small stripped down browsers. Most web designers use XHTML nowadays because it is considered the more advanced way. HTML still works fine though.
