Windows 7 - can an external dvd drive be made to show as hard drive?

I'm new to these forums; forgive me if this is a stupid question.

I just purchased a digital media player, one of those little solid-state boxes with usb and SD inputs. It plays any video format from any storage device I plug into it, a wonderful thing.

However, when I plug my little portable external dvd drive into it via usb, it cannot read the files on the disc. (The instructions for the player says a drive must have "MBR", which I'm assuming is master boot record.) Because I have a standalone dvd player in another room which plays discs containing divx and mpg files, I'd occasionally like to burn my media files to a dvd as data instead of just storing them on a hard drive. So my question is: is there any method of burning a dvd full of video files that will result in that dvd being seen as a regular "MBR" drive when connected to a media player? In all the stuff I'm able to find about making a disc bootable, it's all about pre-loaded things, like a Windows 7 recovery disc or something. I just want to make a disc of my own video files, which will be read by the player as though it were a hard drive. Possible?

Thanks for any advice.

Please post a model number and manufacturer of that digital media player.

Most likely your player is not able to use external dvd drive to play dvds.
These are two different things: to mount a usb drive and to mount a dvd disk into a external dvd drive which also is needed to be mounted with a special driver.

USB ports (inputs) on modern devices like TVs, printers and players generally do not support middleman devices like card-readers and external dvd players, only direct input.

But your case might be different, so again please post a model number and manufacturer of that digital media player.
