I had everything listed by you(and in other threads) except for the VideoLan Repository and libdvdcss. I couldn't find libdvdcss anywhere, and I didn't know the URL off hand.

While I was testing a CD to see if it was causing an error in reading, I noticed that my DVD's name to the system is hda.

MPlayer thought it's name was scd1, so when I went to preferences and replaced "scd1" with hda, I had playback on my DVD's.

The only that doesn't work is menus, but who cares, because it's a breeze to navigate through the chapters.

Thanks very much for your response, and thanks very much to the owners of this fine forum.
