I just installed my BTC DR1108IM the other day, and it worked fine-with certain DVDs. When I popped in other movies, like Van Wilder or Behind Enemy Lines, the drive didn’t recognize any of them. Some work, others do not. Could someone clarify and explain this to me? The DVDs are all originals, not copies. Is this a problem with the drive itself? I even updated the firmware, but still nothing happened. Should I return it? I’m still learning, so please be easy. Thanks again, any help would be appreciated.
