It is possible to get them re-downloaded. I had a hell of a time when I tried to get some game reinstalled on my console. Here's the deal:
When you purchase any Marketplace content, it is registered once with your console and your gamertag. Anyone who uses the content on that console will have access to the full version. If the console is replaced, the purchaser of the content still has access ONLY while connected to Xbox Live. This was implemented so you don't just go off downloading stuff to other people's consoles. It's really pathetic copyright protection, basically.
You can call and complain to Microsoft, and you can/will be successful but I would suggest doing this only if absolutely necessary. Here's why:
MICROSOFT'S CUSTOMER SERVICE SUCKS ASS.
You will have to complain to at least two people, one of them probably being a supervisor. Once you convince them that you aren't

ing around and you want what's yours, they will send a request for however many points you specify to their billing department, or whatever. This request takes a few days. Yes, that's right. A few days, sometimes a week. It's bullshit. They don't just have a button to press that says "refund Mr. Gamer Guy XXXX points."
Now, since you already purchased them on your gamertag, Live knows this... that means you won't be able to re-purchase the item on your gamertag. So you'll either have to give all those points to one of the gamertags on your console or create a new silver account so they can send the points to that one. That way, when you buy the content again, it will register with that gamertag and, once again, your console.
It's a

ing god damn pain in the

ing ass. But if you want them to be able to play the games, if they're wanting to play them, then go for it. It sucks, and you'll definitely end the call with a headache, but at least you'll have full access restored.
Heck... if there's some games that your other tags don't want to play that means you'll have leftover points. That means new games for you.
I haven't called in my points lately (something like 30,000 points they owe me to restore full access) because I just don't feel like putting up with them and my wife isn't interested in any games I've bought, so currently it's not worth it. But you can be damn sure I'll do it in the future.
Good luck to you, and be sure to take some Excedrin before you call MS.
