Sorry, but I know the Chineese are doing it the same way ... :-)

No, this shouldn't work ... OSD is disabled once and for all when there's
no doublebuffering ...

Sorry, I'm behind a firewall and uploading things to a ftp-server is
always a lot of work ... (copying to some location with a real IP ...)

Of course, but once X is running, -vo x11 -bpp 15 won't switch to 15
bits depth ... and as I'm a lazy guy I didn't want to stop the X-Server
... You know with XFree 4.0.x you can switch resolution on the fly ... :-)
(at least for -vo dga :-)))) )

Hmmm, the actual copying should be (a little) faster for the native mode,
but seems the divx decoder is much slower when producing 16 bit output ...

Because in native modes, I just do a memcopy() and when doing conversion
there is much more to be done ...
