Rainbow 6 problems?

while playing, does your xbox freeze on you? this only seems to happen to me after i play a couple of fames and only in StreetsRainbow 6 problems?
I haven't had this problem, but I got Quake IV today and my 360 froze 3 times while playing it. Weird.Rainbow 6 problems?
Every now and then the game will lock up, but very rarely. I can't think of the last time it's happened, but I know it has. A friend of mine has more frequent lock-up than i do on R6 Vegas.
It's frozen a few times, but that happened months ago.
My game freezes whenever I kill someone at the exact second someone kills me (or, less forgiving than that if there is a lot of lag) or when I kill someone with C4 then die within about 5 seconds after that(including suicide with C4).
That stuff happens to my friend a lot and happened to me 2x since December.
Funny you bring this up because I picked up the game about a week ago and I have experienced a few freezes but they have all been online. And actually, I think all have been while someone and I shot at the same time as someone else mentioned.
My XBox freezes alot but never always at the same point in a game, I think its dying again -sigh-. Also, yah that never happened to me when I played R6, And I've clocked a good 50-60 hours into that game so far.
mine likes to give me the ''cant read disc'' error all the time when i go to load up the Tunnels. Just started lastnight. Funny thing is i was playing the Tunnels that morning without any problems.... stupid $400 POS. im all for the 360 but seriously it gets really annoying considering how much i paid for it and what quality it is.
Last night while playing R6 Vegas on 2-player split screen, the left half of the screen was all dark and flickering, as if the lights in the casino were flickering, but it wasn't happening on the right side of the screen! We were standing right next to each other in the game, so the scenery should have been identical, but the left side was barely visible. Then we kept dying/respawning repeat until all of a sudden the system completely froze up! Is this a problem with the game or is my 360 defective??
None of those are as bad as my cousins.. he just got his 360, took it out of the package, plugged everything in, inserted gears of war to have the 3 red lights... he went MENTAL haha.
