The reason I just registered for this forum and am posting now is because I was very concerned about he rumors I was hearing (and experiencing myself since I am an XB Live Beta tester).
Well, my friends and I did some tests and here are the sad results:
What we had:
My Xbox (Modded).
My Neighbor's (Modded and EvoX installed).
My Cousin's (Non-Modded).
My Brother's (Modded and also V1.1).
Moto GP (DVDR)
Moto GP (on HDD)
Moto GP (retail)
Test each Xbox with Moto GP DVDR, on HDD, and retail version (retail version was only version working on unmodded obviously). Each test was only 5 minutes apart (just incase the servers were too flooded with people).
Well, sad to admit it...but here are the results:
The only combination that worked was the Moto GP (retail), on Xbox (non modded).
We did this test this morning and I later did the tests this evening with the same results.
I hope it's fixed
P.S. - We took my brother's Matrix mod out and it still didn't work even after that. That just boggles my mind.
