Hi Rashkae;

Thank you for responding to my email.

I get the same results with all DVDs from that boxed set ( for use in
the US and I am in the US using a DVD player set to region 1 ).   I
tried another DVD.  I got a *slightly* grainy and choppy video....only
slightly ( I have dmae enabled ).

Thank you.  I did that and rebooted, no change.

Ubuntu told me that there is no such file or directory.   I did find
and remove a ~/.dvdcss directory.  I rebooted as well.  No change.

I ran dmesg immediately after trying to run the DVD.

The output was too voluminous to follow it back to the top but at the
bottom I got a message that had to do with the DVD that could not be
read:
