Trouble ripping a non-commercial DVD

[Letsgoterps]

Last year, I received a DVD-R which contained footage shot by the guy who made the DVD-R (so that you understand this is strictly noncommercial). I was unable to rip it, so in exasperation, I went to my friend with a stand alone burner to make copies, which I unfortunately lost, together with the original. I So I finally got a new copy from the same guy and I can't rip this copy either.

When I try to open it in DVDshrink, a pop up window says:

DVD Shrink encountered an error and cannot continue.

Failed to read file "F:\"
F is where my Plextor 716 is.

Any help:
The DVD+R is a TDK 4x
The disc's name (per windows explorer) is LG_RC590M which I assume is the drive he uses.
The first subdirectory is VIDEO_RM:
it contains
VIDEO_RM.BUP
VIDEO_RM.DAT
VIDEO_RM.IFO
The other subdirector is VIDEO_TS:
it contains
VIDEO_TS.BUP
VIDEO_TS.IFO
VIDEO_TS.VOB
VTS_01_0.BUP
VTS_01_0.IFO
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB
VTS_01_4.VOB
VTS_01_5.VOB

It plays just fine on my stand alone Samsung with my TV. When you load it, it has a menu, with one title, you click on the title and it plays. It did not play on my computer in the one attempt I made.

My computer is a Compaq Presario, Windows XP Service Pack 2, my DVD burner is a Plextor 716.

With the prior copy, I was unable to rip it, but could copy the files from the original DVD and play those files on my computer.

Hi!

Since Windows CAN see the contents of the DVD (which appears to have been copied from a DVD-RAM disk and should have NO protection since it's not a commercial DVD), simply copy ('Drag & Drop) the files of the SECOND directory (.IFOs, .BUPs, and .VOBs) to your hard drive - and then use a burning program, such as NERO BurningROM, to burn in "DVD-Video" mode...
