Help- Getting Didigtal copy DVD's of PC onto Droid Tablet and Phone

[JohnMcD348]

OK, I'm still Droid ignorant and trying to learn but haven't been able to find an answer for this. Here's the delima.

We bought a Droid Tablet, Archos 101 G9(ICS OS) mainly to use as a video player and streamer. Our plan was to load up movies onto a 32gb SD(micro HC) card for use during trips and stream once in the motel room ans such. The streaming works OK with Amazon and netflix over WiFi. THe problem is, I cannot figure out how to move the Movies over to the SD Card. When I put the SD Card into computer(Win7 Pro) it won't recognize the card and says it needs to be formatted. I don't want to format it for Windows, or is that a problem? I would think a Windows formatted SD card wouldn't work on a Droid device.

Is there a program out there that would help me move a digital copy movie over to my tablet, or her phone even for that matter. When I plug in the tablet, the Computer does recognize it, but does not allow me to transfer items over to it.

I'm stumped. Thank you all in advance for the help.
