df_video and df_video_particle use RGB.

The feature should be handled by the DVB driver
to produce other YUV formats, e.g. YUY2.

Argh, that's the cause. The G200 only supports YUY2 and I haven't added
that extra check in the driver yet, sorry.
>From matrox_bes.c:
if (config->flags & DLCONF_PIXELFORMAT)
switch (config->pixelformat) {
case DSPF_RGB32:
max_width = 512;
case DSPF_RGB15:
case DSPF_RGB16:
case DSPF_YUY2:
case DSPF_UYVY: /* FIXME: not supported on G200 */
break;
default:
fail |= DLCONF_PIXELFORMAT;
}
else
if (layer->shared->surface->format == DSPF_RGB32)
max_width = 512;
I will have a deeper look into the SAA7146 docs.
The only way to get it working with YUV on your G200 is to add
support for YUY2 to the DVB driver. You could try a BTTV just for
debugging, but that's probably not the card you want to watch TV with ;)
