Playing DVD movies

[lhunsicker at mchsi.com]

Good evening again, folks:

One of the other last glitches is that I can't get ubuntu to play the movies
from my DVDs.  The Movie Player is working fine on files on my hard drive.  But
when I direct it to my CD/DVD reader, it tells me, "An error occurred.  Could
not read from resource."  

When I use the File Browser, I can see the files on the DVD just fine.  But
obviously this DVD intended to be read by a windows machine, as it has two *.exe
files and an autorun.inf file, and then two subdirectories.  

If I open totem and then try to open one of the files in the VIDEO_TS directory,
totem tells me that I need to add some codecs, but it doesn't tell me which ones.

Any suggestions, anyone?

As always, thanks in advance to anyone that can help.
