If your burned dvd works on the computer, then you may be closer to a solution than you think. It sounds like you have copied it correctly, but your stand alone player is a bit picky on burned disks.
First thing to try is to slow down your burning speed. If you have been using 16x media at max speed, slow down to 8x. If that doesn’t help, buy high grade disks…like Verbatim 16x and burn them at 8x or 12x speed.
As far as tools for decryption, ripping and compression are concerned, you can still do this with entirely free tools if you wish. DVDFab HD Decrypter is updated regularly and can break encryption for you and rip to the hard drive. (this is the free section of DVDFab and it will continue to work even after the 30 day trial of the main section is finished). DVDShrink is free to use also and can compress your movie to fit a dvdr. I also recommend getting ImgBurn for the actual burning to a disk…it is also free.
