When I first purchased this drive, it came with the region code unset, as opposed my Pioneer DVD-106s and other no longer living drives of mine that came preset to 1. I came with 4 changes remaining and setting it to 1 of course knocked me down to 3.
It came with a 1.0something firmware, I've since upgraded it, follwing directions exactly, to 2.0a, then 2.0b, and now finally 2.0c.
I went to play a movie with it and was told that I had to set my region. I checked device manager and found that my region setting was now "Not Selected" and i only had 2 changes remaining. I set it to region 1 and now have 1 change remaining.
I haven't changed my region code, nor has any program done anything that would suggest to me it was doing that. I rarely watch movies on this drive, rather I use my Pioneer drive, so I don't see why the Sony would be affected and not the Pioneer.
I emailed Sony Tech support and will post their response if it's it all helpful.
In the meantime, has anyone else had issues like this with this or other Sony drives?
