In the past, on another system, gl and gl2 were too slow to play
HD movies. However, I just tested with a 1280 x 532 Matroska file
(H264 + AC3) and it was able to stay in sync. So I suppose that I
do not really need this new renderer right now.

gl2
A: 519.0 V: 519.0 A-V: -0.001 ct:  0.003   0/  0 54% 13%  1.6% 84 0 41%

direct3d
A: 395.1 V: 395.1 A-V:  0.001 ct:  0.002   0/  0 56%  4%  2.2% 43 0 46%

directx
A: 402.1 V: 402.1 A-V: -0.006 ct:  0.000   0/  0 54%  3%  1.0% 18 0 41%

To answer your earlier email: updating my video drivers helped.
Thanks. There is no repeating now. However, -ao win32 is worse
when vo == direct3d. In that case, there is a slight pause (a
fraction of a second) near the start. For example, audio that
starts with "my name is" sounds like "my<break> name is". 
Otherwise, the combination of vo and ao does not matter.

And yes, it seems that vo initialisation is slow. The audio
starts to play before the MPlayer window is displayed (direct3d
and directx) with both -ao dsound and win32. It does not happen
with -vo gl or gl2.
