syntax highlighters

sorry if i’m missing the boat on this one but i’m struggling on this one: i’m looking for a plugin (or something) that will let me add code to a post but not slaughter it by encoding the html entities. i’m using the html view of tinymce but, every time i save/update a post, the code and the quotes, ampersands, and such get encoded and then encoded again.. etc.

i’m currently using syntaxhighlighter plus (and tried evolved) but, while it’s great on the highlighting issue, it doesn’t solve this issue.

is there anything to do about this? or is this life?
