How can I play a .drv file I received several .drv files recorded from a security system's cameras. The disc provided to me includes a player called "GenAVplayer.exe" and a filed named "player.bin" which when expanded contains .dll files, I assume various codecs for the player. Does anyone have any suggestions as to how I can play these video clips on my Mac?

Thanks in advance.
I would recommend either MPlayerX or VideoLAN. Both are freely downloadable and support a variety of audio and video codecs. If you're lucky one might just work!
