My problem is the computer is a laptop with the I915GM chipset (dell
inspiron 2200) that for $400 makes a great mobile mythtv display.
It's just a driver bug that's not too hard to fix as the hardware can
create a 1920x1080 overlay but was coded with the old i810 limits into it.
With the mythtv patch it won't crash my backend when a remote display
errors. Great work guys!!!
