There's no such thing as "Linux format" video. There are numerous video formats -- different encoding formats (codecs), and different container formats (mpeg. wmv, mov, ogg, etc.), and so on. Most can be viewed on any operating system, if you get the proper codec and container software.

What are the filenames -- in particular, the filename extensions -- you think are "Linux format"?

The DVR is likely using a Linux OS File System. A USB drive must have the proper File System for a particular OS to read and write on it.

File System Formats that both Linux and Windows can read are limited. My suggestion would be to make sure the USB’s File System is FAT32, which can be read by Linux and Windows. As I stated in my posts, there is a limitation of 4GB per file. There is a format called exFAT that allows for larger file sizes, but the Linux System must have FUSE for it to read it. As we don’t know the details of the DVR’s OS, that may not work.
