DVD readable on a Mac but not my PC?

[TechShark]

My friend burned a program for me on a DVD, and before i left with the DVD we checked to see if the information copied over correctly and it looked like it did fine on his MAC, but i took it home on my PC, and the DVD's appear to be empty.

anyone have any idea why?

It depends on how he/she burned it. If they burned the DVD as an image file, it is probably incompatible with Windows, and therefore Windows reads the disc as empty when it in fact has data on it, Windows just doesn't recognize that data. Have your friend re-burn it on the disc as a .iso or other windows image disc and test it.

Didn't read the question right. The answer above is if it was an actual DVD movie. I guess the only other thing I would try is to try sending the program via internet or burn it onto a different disc and try again. Or test the current disc on another mac. It might be as simple as him not finalizing the disc.
