ecml and embed_extender... embedding videos

i just noticed that a youtube link that i had added to a blog post long ago is no longer being correctly handled and is not rendering a youtube video (via the embed_extender) plugin.

i played around with embed_extender and was not able to resolve the issue.

i thought i would disable embed_extender and just do a normal embed. however, htmlawed is removing the iframe object.

so then i though i would look at the ecml plugin, since i want to use it anyway.

i could either use ecml to embed a videolist video (from youtube) or directly embed a youtube video (without using videolist). i looked in the readme for ecml and the example is given for embedding a youtube video. however, this doesn't work - and the word 'youtube' is not in the ecml plugin anywhere currently.

so what is the solution here?
