I've no clue what your problem is, but I did some poking around (it
sounded interesting).  Here's what I found:

- DirectFB is a video driver layer (direct frame buffer), similar to
MS-DirectX (or at least that's how they describe it)
- It should be compatible with V4L (video for linux)
- videoout_directfb.cpp and videoout_directfb.h are part of the MythTv
source code (that's a good sign)
- Your error starts at:

(!) DirectFB/fbdev/vt: KD_GRAPHICS failed!
--> Operation not permitted

, which sounds like a permissions issue.  This is the only thread I
found on the subject:

Also look at:

, maybe there's some clues there (or a fix)

It doesn't sound like he's working on the same thing you are, but maybe
it's the same root cause.  Good luck,

PS - DirectFB/fbdev/vt does not exist on my Linux box (Slackware 9.1 -
if that means anything??)
