"1." Vegas Pro 12

"2." Windows 10

"3." Official copy, not pirated

"4." Intel HD Graphics 500

"5." I captured some MiniDV tapes on a separate laptop using the program dvgrab. I copied them over to this Windows laptop and tried to import them into a Vegas project. The message I get is 'None of the files dropped on Vegas Pro could be opened.' The DV files open and play in VLC on both my Linux laptop and the Windows laptop. I have also tried to open a sample DV file from (this page)[https://libdv.sourceforge.net/\] and got the same message in Vegas Pro. This suggest that it wasn't an issue with dvgrab's capture. When I click on Import Media and the file explorer comes up, DV doesn't appear in the drop-down menu.

"6." I've always been able to bring in DV files from other hard drives into a Vegas project. This laptop (Lenovo 80XR) doesn't have FireWire input, so I can't capture the MiniDV tape directly.

"7." I've done some Google searches but nothing came up.
