Greetings, Long time user of AnyDVDHD. Recently, I have been getting this warning (maybe the last 6-12 months). This now happens more often than not. Yes...my optical drives are both set to R4. This matches the region of the disc. Here is the kicker - if this warning pops-up, I swap the discs between the 2 optical drives and it usually DOESN'T re-appear. I believe this is a small bug. It always seems to happen when one of the DVD's has 2 or more region codes on the disc. In this case, one of the DVD's had both R2,and R4 on the disc. I have included log of the last two discs this happened on. Thanks.
