Are you outputting to a TV? Is that an interlaced modeline? Something like the
Modeline "720x576" 12.85 720 752 800 832 576 589 592 605 -hsync -hsync
I experience no such issues with progressive DVDs, yet I have both bob and
and OpenGL vsync enabled.
I actually only need bob enabled for stuff recorded from my PVR 150. For DVDs
and DVB recordings it's not needed and I have noticed that the picture
quality drops a small amount on DVB and DVD when I have bob enabled.
