.dmg vs. cdr

What is the best disk image format for archiving DVDs? It seems like my back ups vary between .dmg and .cdr formats. I do not even know how I choose between those two when I create my images.
I would also like to know what are the best options to choose from the pop up menus such as Encryption, Image format etc.
I just would like the best way to save my projects for the next few decades in case I need them.
Thank you,
Ildiko

Although the technology keeps improving, DVD video is meant for viewing, not editing. If your need in the future is re-editing, highlights, etc. the challenge is different and involves storing big video files on hard drives or exporting to videotape. Could you clarify what uses you anticipate for your projects?

I do not intend to edit these projects in the future. I will use these back ups only if my DVDs get damaged over the years and need to create a new one to put into my DVD player and watch them on TV. These projects are family videos that will be valuable forever.

Thank you,

Use a disk image. It is an accurate copy of your DVD, you can make copy DVDs from it also.

Burn your family DVDs to 'archive grade' DVD-R media, for example Verbatim GoldArchive, which have a more robust coating.

Klaus:

I have been using plain Sony DVDs to burn my family videos. I assume they are not as good of a quality as your recommeded Verbatim GoldArchive. Should I reburn my projects to the Verbatin so they last for the next 50 years?

Hi

Me just thinking.

Do You think that there are any DVD-players and TV/Screens that can playback
in about 50 years ?

How about 78-rmp stone cakes records. Yes i got a turntable still working
but not many friends does.

Probably not, but my view is that it is important to preserve your family videos in any digital format on secure media so that in the future someone can convert them to whatever is in use at the time.
