That seems to have worked (I used the GUI frontend gmplayer to change
the driver to the setting "X11 (XImage/Shm)"), but it displays letterbox
bars on the playback/image, despite the DVD in question being a
conventional 4:3, "fullscreen" TV program (and making the picture
slightly "off"/"squished" looking from my perspective), where it didn't
do that under the old setting. Any suggestions on fixing that (selecting
the "4:3 ratio" setting didn't do anything)?
