All you have to do is click on the disc that it mounts to your desktop and copy the files to where ever you want to keep them.
To play them......open up DVD Player and go to File(I think, not at my mac now)> and click "play TS_Video File". Then just select the folder you copied and thats it.
I was searching for all these compression things like DVD2OneX, etc. you all saved me a lot of time. I'll just put the files on the HD and when done, delete. thanks
