recommended youtube / video embed plugin?
 

I'm finding that I have little control over embedded youtubes. They get picked up automatically and left aligned at a standard size. I would like to have more control and prefer they would center by default. Can you recommend anything? The only way I get them to center now is by going to html mode and adding a <center> tag but it seems to work only sporadically for some reason. I also often have posts that show centered on the front page but not on the direct link to the post. Either that or other times it just shows up as the text of the link and doesn't actually embed. The whole thing seems to be very finnicky and sporadic.

Would love something that handles vimeo too.

Thanks.
