Titanfall HD content won't download on xbox 360

I have been having this problem, but it progress to texture and sound degradation in game. Makes it virtually unplayable. I have been trying to keep track of every possible step I take. This is from another thread, ( http://answers.ea.com/t5/Titanfall/Help-Major-texture-and-sound-issues/m-p/2651620#U2651620 ) but NONE of it has helped.

OK, EA Bastian, here is what I did.

Popped in a new HD. Clean, reformatted 60 gb. Started from scratch with everything. Removed any other components withing a 3ft radius. Put in Titanfall, downloaded update. It began "optimizing hd content." Changed options to 30hz. Started training, did not complete training. Played 2 games with no issue. Shut down.

Restarted, it did not say it was optimizing hd content for the first time ever. Hooray! Played 2 games, no problem. Shut down.

Restarted, it did not say it was optimizing hd content. 1/2 way through 1st game, everything went wonky and textures broke down. Shut down.

Restarted, it now said it was optimizing hd content, 1/2 way though the 1st game, everything broke down. Then I broke down, weeping uncontrollably.

I couldn't have started any cleaner. I really hoped it would have fixed it, but it didn't. I'm at a total loss now. Any ideas?
