Comment(by laga at laga.ath.cx):

 Hi,

 I'm using an interlaced PAL modeline to drive my TV:

 {{{
 Modeline "720x576pali" 13.88 720 726 794 880 576 580 583 625 -hsync -vsync
 interlace
 }}}

 My video/osd render method is opengl. When i'm trying to use the normal
 (software) bodeint, i get the following messages:

 {{{
 2007-09-07 15:44:48.131 VDP: GetFilteredDeint() : opengl -> 'bobdeint'
 2007-09-07 15:44:48.132 VDP: GetFilteredDeint() : opengl -> 'bobdeint'
 2007-09-07 15:44:48.133 Failed to approve 'bobdeint' deinterlacer
 2007-09-07 15:44:48.134 Couldn't load deinterlace filter
 }}}

 However, the hardware bobdeint works:

 {{{
 2007-09-07 15:42:36.081 VDP: GetFilteredDeint() : opengl ->
 'openglbobdeint'
 2007-09-07 15:42:36.081 GLVid: Creating openglbobdeint filter.

 2007-09-07 15:42:36.091 GLCtx: Created frame buffer object (720x576).
 2007-09-07 15:42:36.092 GLVid: Turning off deinterlacing.
 2007-09-07 15:42:36.092 VideoOutputXv: Using deinterlace method
 openglbobdeint
 2007-09-07 15:42:36.092 GLVid: Turning on deinterlacing.
 }}}

 Prior to the mythtv-vid merge, bobdeint would never work for me because my
 refresh rate was too low. I had to use the patch from #2903 to enable
 bobdeint (without a deinterlacer, I would get interlace
 artefacts/stuttering despite my video resolution matching my display
 resolution - same happens to a lot of other people, too). Now I'm kinda
 confused by this discrepancy - is it intentional that openglbobdeint works
 while bobdeint does not?

 I should note that I'm using a Twinview setup. CRT-0 is a 19" CRT monitor
 running at 1280x102, CRT-1 is my TV running said modeline.
