Well, you CAN go to a terminal and (as root) use the hdparm command to
reset the DMA but, of course, you will miss a portion of the film during
this step.


Why "of course"?

I don't know how you manage it but if you are watching a DVD and have to use the hdparm command then going to another desktop to start a terminal or do, say, CTRL-ALT-F2, logon as root and issue the command you miss a portion of the film. You can hear the audio but you don't see the video- hence you miss a portion of the film.


I did change that setting while copying files, and did not loose a byte. The only thing you could notice is a glitch, a delay, while the kernel activates the change: if the viever reacts to delays by dropping frames (which is a normal trick, by the way) then yes, you will miss a portion.
