Double Dragon...BROKEN?!?

I've tried about six times in a row and can't get an xbox live game working for longer than 15 seconds before it kicks me out and says "lost connection".  What the hell is going on here.

Also, when there are more than three or for characters on the screen, the game slows to a crawl.

I can't believe they messed this thing up, it's as bad as the street fighter mess. 

I downloaded it right after the update. Then I went to bed. I'll have to check it out tonight

when I get home from work. If it is broken they better make an update fast! 

The arcade original of Double dragon had slow down when too many guys were on the screen.  If it's just a dump of the old code then it could still do same thing.  I believe it's a programming issue not a hardware one.
