I use DVD Shrink which is great for ripping to my laptop hard drive. However I recently got a Freecom Mobile Drive XXS 320GB Portable Hard Drive.
I wanted to rip straight onto this, but it rips into 5/6 different files. I'm not sure how then to use ImgBurn to burn these or watch them from my laptop using something like VLC media player.
If I try and cut and paste the 4.5gb file from my laptop drive to the portable drive it says there is not enough free disc space, which is definitely not the case.
If they are the video_ts files, then they didn't get put into a folder. When you save the files after compressing, they need to be saved to a folder. I usually set up the folders before compressing to them.
What os are you using? I have xp and use either 'copy to' or 'move to' for the files I want to transfer.
