What about thanking poor Nailed for responding. Doesn't he get any thanks or respect for responding in the way you desired? I need to back BJ up on the "do your homework" blurb. But also, how about try sh!t yourself. What have *you* done to remedy or troubleshoot the issue. You've made a start with the "Well the DVD plays fine... blah blah". Now we're all guilty (myself included) of posting a question w/o doing as much as we could have on our own (if anything at all). But it's funny how you took the effort to respond to BJ's response instead of posting everything you've done or every detail (as you later add on that other games are having the problem as well). (Maybe it's a bad cable, bad dvd drive, bad hard drive, pilot error, etc), what did you use to copy, boXplorer (my personal choice), xbcopy, osmosis, etc.. I again agree with BJ on the what's really "ruining" the board.. granted, I kind of don't really care because I just weed past the bullsh!t, so to each his own...
Also, other things to think of.. did it ever work? if so when did it stop working? (after you f'ed with the insides and you really shouldn't have been?). Is the hd a new drive or one you had laying around? Does it make any noises? does it smell funny? (ok, I'm kidding on the last one)..
