I'm having problems burning my iso back ups

I have burned 2 xbox 360 games first time no problem, they were on my computer hard drive but I have a few games coppied onto my dad computer but he doesn't have a dual layer burner, I coppied the files onto an 8Gig flash pen to transfer it to my computer for burning, non of them have worked, I'm doing everything the same and even checked the files on abg360 and they seem ok, does anyone know what could be wrong? it seems wierd that the first 2 games I did on my comp worked fine but the ones I transfered from my dads comp first don't, is it just a coinsedence or is the problem happening because I am transfering it?
