Can I reuse my Passport for Mac as storage for movies?

I hope someone can help me with this. I have Dish Network and recieved a new reciever from them. I was told if I wish to save any recorded movies I would have to get an external drive. Is there a way to use my Passport for Mac to store movies from Dish? I realize that all the computer backups I currently have will be deleted but willing to do that and need a larger ext drive anyway. Appreciate any help!

Hello and welcome to the WD community.

From what I know, DVR’s use some kind of proprietary file system on which you cannot copy files from an external drive to the computer. But you can try to contact our cable provider to see if this is actually possible? I see no problem with connecting a USB drive to the DVR, but copying the files to the drive and then to a computer.
