My girlfriend and I went out to Blockbuster earlier, had snuggled up with seats right next to my monitor with The Omen, I went to play it in Mplayer, but instead of seeing Damien, I saw this:

Playing dvd://1.
Reading disc structure, please wait...
There are 19 titles on this DVD.
There are 21 chapters in this DVD title.
There are 1 angles in this DVD title.
libdvdread: Invalid title IFO (VTS_04_0.IFO).
Cannot open the IFO file for DVD title 4.

Exiting... (End of file)

I recompiled and installed libdvdcss and libdvdread; no avail.
Thanks in advance for any help.

Your first problem is painfully apparent - you are running as root, you haven't installed any fonts or codecs. Try running it as your regular user. You do have a regular user, don't you?

Yes, I do. I just ran it as root instead of chmodding /dev/dvd to be run as the user.

Try opening the individual files under gmplayer - it could be that it's just not picking up the first file on the dvd.

I didn't install gmplayer; however, I did try playing each VOB with mplayer.

VIDEO_TS.VOB: Opened; video played, but was far too fast.
VTS_01_0.VOB: "FATAL: Could not initialize video filters (-vf) or video output (-vo)."; also, I scrolled up in Eterm and saw this: "It seems there is no Xvideo support for your video card available." That struck me odd, as I have watched other videos (given, not in DVD format) in Linux.
VTS_01_1.VOB: "Seek failed"

For each VTS_0*_0.VOB, I get the same "FATAL" error; for each VTS_0*_[*>0].VOB, I get the same "Seek" error.
