Oh. I see. OK: you were mailed DVD discs, in a cardboard envelope, no doubt.
Not a 'DVR', which is a box that records video information.
To transfer off of those DVD discs, you'd need a DVD drive on your computer.
Not just a CD drive, but one with DVD disc capability. If it says 'DVD' in embossing on the
cover or front of the drive on your computer, then it is a DVD drive, and can read your DVD discs.
Locate pictures on one of those DVD discs, once it is inserted in your DVD drive, and reading OK.
Select a picture off that drive, then copy it to ... anywhere you want it on the computer, such as a special folder, or esp. a special folder in the
area, where it would be easy to find again.
Does that make sense of the process?
