I have tried to play gta 4 the lost and damned on xbox live, but I dont know how to play it on xbox live?

On the Xbox Live marketplace, you are able to download Xbox Originals directly to your hardrive. I was wondering, can you use cheat codes on those downloaded games?

I have an xbox live account that is currently silver because i decided to get a new one, but i have over $75 worth of downloaded content on my other xbox live account and i cant get it to work on my new one. I have both of them on my harddrive on the same xbox. How do u get the content to work on my new one?

I have my 360 up in my room, but my computer is downstairs and i want Xbox Live without playing downstairs or using a wireless connection. All Ideas are welcome.

My headset is broken, and I need to talk in XBOX Live. I have a rock band microphone. Is it possible to use the rock band mic to talk in xbox live?

I have a XBOX 360 and i want to connect to xbox live but in my house there is no internet connection.

I have gathered over 10,000 achievement points and I want to know how i upgrade my xbox account so i can go online and keep all of those points.

Mistakenly I set up a new profile for joining xbox live instead of using my extensive one i’d been using (which had a Gamerscore of 4000). Is there a way to transfer the profile and Xbox live account ive set up (which has a gamerscore of 0) to the other profile on the same Xbox? Or can i transfer my details like achievements and games played onto my new xbox live profile? I had heard this can be done at a cost of 800 Microsoft points.
