Help with Mediahome and xbox360

I can’t get my xbox360 to find mediahome. This is what I tried.
First I updated Nero6 to get the Mediahome program. Mediahome sees the 360, but the 360 doesn’t see mediahome. Then I downloaded Nero7 trial because it said it supports the Xbox360. Now, when I start the mediahome server then turn on the xbox360, a popup appears and reads, a new device has been discovered and allowed by nero mediahome. Then I get a windows errror reading, NMMediaServer.exe has encountered a problem and needs to close. I didn’t get any of these errors with Nero6, only with nero7. The 360 didn’t see mediahome as I stated before.
I am running Windows XP home(not WMC).
Thanks to all
