I have rewritten the osd-procesing parts. Now the dxr3-plugin imitates the
dvb-ff osd commands.

orginal fomr dvbosd.c:
Cmd(OSD_SetBlock, Bitmap->Width(), x1, y1, x2, y2, Bitmap->Data(x1, y1));

code in dxr3plugin:
Spu->Cmd(OSD_SetBlock, Bitmap->Width(), x1, y1, x2, y2, Bitmap->Data(x1,
y1));

This makes things much easier. In the pre2 i am also using optimced -
depends on cpu -
memcpy command.

Here a little preview history:

2004-0?-??: Version 0.2.3-pre2 (now aviable on SourceForge)

- fixed audio and video problems
- works now with vdr < 1.3.7
- added YUV2Rgb int dxr3tools.h (for dxr3spudecoder)
- added some more debug infos in dxr3outputthread.c
- added const keyword in dxr3configdata.h
- added EM8300 include define in Makefile
- added debuglevels, so we can define how much we want to log
- assimilated spudecoder from vdr's dvbspu.c/h -> nice nav in dvds
- kicked out cDxr3InterfaceSpu from dxr3interface.c/h
- a little fix for cDxr3Interface::ResampleVolume
- kicked out dxr3interface_spu.c/h and dxr3interface_spu_list.c/h, because
  the new spudecoder dont need it anymore.
- added dxr3cpu.c/h to get some infos about the cpu
- added dxr3memcpy.c/h to get a little speedup - i hope
- maybe a little audiofix: lastHeader in cDxr3AudioDecoder will now set to 0
  with the constr. and not via Init()-function. So there should be now some
lesser
  audio scratches.

But there are some things i want to bring in the pre2, for instance, grabing
image.

This fix will be in the pre2. I am working now on the colormanger, to fix
the artefacts,
so that i hope the osd looks like the osd of a dvb-ff card.

Thanks.
