I just thought I would post this, in case anyone else was having this problem (and since I searched and didn't find a thread that came to the same conclusion I did). When I installed OpenBSD (and used the intel driver), the only issue I had was that HD video was choppy and exhibited a lot of screen tearing. After playing with my xorg set up, here is what I ended up adding to my xorg.conf to correct it:
Code:
Section "Device"
Identifier "IntelGraphics"
Driver "intel"
Option "AccelMethod" "sna"
Option "TearFree" "true"
Option "TripleBuffer" "true"
EndSection
Section "Extensions"
# fixes tearing with vdpau/vsync
Option "Composite" "Disable"
EndSection
