youtube integration

have one site (misterxrocks.com) which we use to generate some content and am trying to have the news also popup in a second website (st5adtla.com), but the youtube links never show up in the new posts. please help! spent the past several hours trying to figure out what i was doing wrong but i’m kinda lost. does the RSS reader ignore <iframe> tags? appreciate any help!

this is what it ends up looking like:
