Doesn't work, yet. VDR can only use full-featured DVB-S cards for output
(But low-budget-cards-only-system works for recording). When the
API-version of VDR will be stable, some will write plugins for DXR3.

We already considered to patch VDR to send the A/V-stream to stdout
muxing in the OSD as SPU for using player like MPlayer as backend, but
SPU is limited to 4 colors and DVB-OSD needs more.

Are the kernel-sources and links to them all right?

If I2C is compiled into the kernel, you can ignore the error-message.
It will work. For videodev, you need to have support for the V4L as kernel-module.

There were problems with old stuff in the driver. I never had problems
with GCC2.96, so some old EGCS-stuff might be left. Someone posted he
was about re-writing the old stuff, but I think other can tell you more.

You have to write a nice patch or wait for the plugin-API. The problem
will be to port the OSD.

You mean subtitles and OSD with DXR3? As for MPlayer has working OSD and
subtitles, but I don't know if it's implemented for DXR3.
