Thank you Dirty_Maineiac

Finally someone responded reporting the same issue...I have been following up on this issue for  quite sometime, and only now I have received some responses from some people. Thank you..

I dont get the ""DISK READ ERROR" message though..Thats interesting cuz in some cases it can also be a problem with the blue ray disk reader. But you can confirm this by playing some other games or playing blue ray movies and see if you have the same problem..

There is also another interesting note I read somewhere in some blog and I think this may be a cause of this problem as well. If you have noticed, MW3 does not install its game data. It only installs the Patch. Usually, a lot of games, when you put the CD it, it installs some of the game date to the console first so it doesnt need to read the CD all the time. However, in the MW3, the CD is always running to keep the data readable and maybe this is the reason why MW3 is the only game causing the problem and it freezes on some console in the middle of MP gameplay. People have reported similar problem with MW2 before as well but I couldnt find any solution for that. So I am assuming they may have fixed the issue with a patch or something.. not sure since I didnt have Mw2...However, I thought it could be another reason for this problem. Not sure...just an idea..

Anyhow...I also got a response from another bloke in the PS3 forum yesterday. He said that he had the same problem and he fixed it by disabling the theatre mode. Apparently the PS3 hasnt frozen for him since then. So it may be worth giving a try...I will be trying this as well and I'll update on how it goes in the next few days...Here is the link, you can have a read at this suggestion: http://community.eu.playstation.com/t5/PlayStation-Network/Ps3-Hangs-Modern-Warf are-3-Multiplayer-Constantly-Freezing-my/m-p/14280413/highlight/false#M571

thank you kourtvizion,

i actually did try to reach Activision. Thats the first thing I did and this was 3 weeks ago. Once I sent them an email, I received an automated response saying that there is generally no problem from their end other than the Elite prob that there were fixing at that time. And then it said that someone will get back to me regarding my enquiry once they have a solution. And there has been nothing since then and this is what is pissing me off. It does not take 3 weeks to get back to an email.

I also tried their online chat support as well. I was waiting for over 1/2 hour on 3  different attempts and eventually gave up. What can I do? Thats why I have no other option than to follow up on the forums..

I do thank you for reading my post and for ur response. I know what you mean by the network settings. I have set-up static IP address for this console and have also added this to the DMZ and the NAT settings are open. I dont think there is anything more to this...unless I have missed something. But thats one of the first thing I checked. I do realise that a lot of people in the forum claim that they did everything and nothing works but actually they might have done nothing more than restarting the console. But thats not the case with me...I literally tried everything..

Anyhow, I will go back once again and re-check the network settings again just to be 200% sure....Thankx again man...

I have resent another email to Activision once again..fingers crossed!

hi kourtvizion,

i just tried to play this stupid game again and it still hangs. I tried 5 times and it froze 3 times out of that...I am so heart broken..i was hoping this **** was fixed.

i also tried what the other bloke in another forum suggested that is disabling the theatre mode and that doesnt work neither... :-(
