PC Compatibility with iDVD produced DVD

[Daniel Beck]

I was asked to make a DVD out of footage my friend took on a MiniDV 
camera. I captured it with FCP and marked chapters and exported it as a 
FCP movie. Then imported it into iDVD3 with no trouble. After burning 
it on my 12" PowerBook, it worked fine on my PowerBook. However, I 
received this message from him today:

Begin message:

Anyone know why his PC didn't recognize it? Should it?
