I have sonic DVD plus preinstalled in the computer. I installed Nero7 in my computer,after successful installation of nero , sonic would not work- microsoft error reporing window opens saying that mediahome.exe failed to initialise. I restored my system to earlier date which resolved the problem. I already have nero 6 on my computer and have had no problems with it. - The same problem happened when i installed IE 7 RC. I had to restore again.Can anyone help?
