Flashplayer embedding, classid vs type="application/x-shockwave-flash"

Question

Which is the better way out of the two to embed a flash player?

<object id="flashplayer" width="800" height="600" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">

or

<object id="flashplayer" width="800" height="600" data="player.swf" type="application/x-shockwave-flash">

Are these the same essentially, or is one more efficient than the other

Answer 1

<object id="flashplayer" width="800" height="600" data="player.swf" type="application/x-shockwave-flash">

needs to be your best choice as it uses html code to define object type.
