I'll follow the instructions on mythtv.org and get you one sometime this
week. I just wondered if any of the commits between 24220 and 24258 had
been specifically targetting a known DVD segfault, in which case I might
have saved myself the time (but probably better safe than sorry, anyway).

Nope, my TV/monitor (a Philips 32" LCD TV, connected by a VGA D-sub
input) has no overscan. The edges of the ubuntu desktop and the edges of
the screen coincide perfectly. However, in the screen setup wizard the
bottom right triangle still starts way out of sight off the bottom right
of the screen.
I first encountered this on my uncle's TV, using component input. His
setup did need correcting for overscan, and bringing the bottom right
triangle into the visibly correct location resulted in a screen area
which was way too small, with desktop showing at the bottom and right.
When I eventually found the correct setting by trial and error, the
bottom right triangle was completely out of sight off the screen.
On my monitor, MythTV displays correctly with the default setup (i.e. no
correction from the Screen Setup Wizard), and I just went to the wizard
for testing purposes. If I do move the bottom right triangle so its
point is in the bottom right corner of the screen, this corresponds to a
reduction from 1280x768 (the native display resolution) to 1180x662, and
I get a big band of desktop around the edge of MythFrontEnd. I note that
this is a shift of -100x, -106y, which corresponds exactly to the size
of the marker triangle. I suspect that on my system, for whatever
reason, the bottom right marker is being plotted with its top left where
its bottom right ought to be.
In a possibly unrelated issue, I also note that although I leave the
"offset" at 0x0, the adjusted screen shifts downwards to reveal the
Gnome menu bar at the top of the screen.
I'd consider both of these to be faulty behaviours, but I figured I
should post here first in case the fault is mine, not MythTV's.
