DVD-RAM
DVD-RAM has the best recording features but it is not compatible with most DVD-ROM drives and DVD-Video players. Think more of it as a removable hard disk. DVD-RAM is usually used in some DVD Recorders.
DVD-RAM is more of a removable storage device for computers than a video recording format, although it has become widely used in DVD video recorders because of the flexibility it provides in editing a recording.
It's often recorded in a cartridge, and is often used for DVD-recording camcorders.
As far as I know, it's still M2V video ... so it looks good to me. =) I should be able to rip the video from a DVD-RAM disc.
