Hello,
I come here hoping for a solution to the following problem I have:
I had some old VHS tapes digitized by a specialized company. The films were digitized and then put on DVD-R.
These are in UDF format.
Out of 12 DVD-Rs made, all are readable on our home player.
However, on my iMac, 6 are opened and read; the other 6 are recognized as blank by my iMac (running OS 10.12.6, Sierra), and cannot be opened, let alone read. Even with VLC software, I cannot play them since they do not appear on my desktop, being considered blank! No software could read them for the same reason.
Does anyone know this issue? Is there a solution?
Thank you in advance.
Best regards.
Configuration: Macintosh / Firefox 72.0

Hello, the UDF format was used to function like a hard drive or a USB stick.
"Packet writing allows CDs to be written partially using fixed or variable size records over multiple sessions. Variable size packet-written CD-RW and CD-R can (typically) be 'closed' in ISO 9660 format simply by writing the table of contents to the CD.
It doesn't really help you
ask your provider why they are difficult on Mac
And I found this:
UDF on a standalone DVD player?
The UDF (Universal Disk Format) allows CDs and DVDs to be used like external hard drives and to copy files via simple drag-and-drop. However, while this disk format is recognized by Windows, it is rarely recognized by standalone DVD players. To watch your movie, you need to burn a new disk in DVD-video format. To do this, create a folder titled MyDVD in your My Documents folder. Copy all files from the VIDEO_TS folder of your UDF DVD into it. Then start your burning software, specifying that you want to create a DVD-video. Locate the VIDEO_TS folder that appears in the empty tree of your DVD-video project and drag the files you copied into the MyDVD folder into it. Another folder named AUDIO_TS sits next to VIDEO_TS. Leave it empty: it is not used by DVD-videos. Finally, start the burning process. You will get a disk that can be read on any standalone DVD player.

Be sure to mark your message as "resolved" if that is the case.
