It's more likely to be a hardware issue than a software issue. Things to try:
1. An external drive
2. Replace the drive.
I have a video DVD that was burned and finalized on a professional DVD player. The source was a video camera, recording a live event.
The first time I had it in my laptop I checked the files in Explorer and they were the regular _TS folders and .VOB files that you find on regular video DVD's. When I opened the DVD "with VLC Player" from the shortcut menu it opened and started playing, but the video was squished horizontally so it was framed like a vertical cell phone video. Once I changed the aspect ratio to 16:9 it was fine.
I was having some other video issues (not recognizing external screen) and, because of previous experience, figured this was related to being connected to some other video equipment under test a few days ago. I uninstalled my video drivers and rebooted. Windows automatically downloaded and reinstalled the drivers, and my video problems were fixed.
Now, back to the DVD. I tried opening the drive in Explorer again, but there was no response. I tried ejecting and reinserting the disc, but the drive spun up and down a few times, then decided there was nothing in the drive. The drive still reads a commercial DVD ok, but I can't figure out why it stopped recognizing this burned video disc. Could it be related to the video drivers?
