I now have an Epia MII-12000 and I'm in the process of setting it up.
I'm assuming that others on here have tried these things so I thought
I'd save a bit of time and share the answers with others who may be
interested (and Google didn't really give me any straight answers!).

As I understand it, there are two methods of getting accelerated MPEG
decoding with vdr:

1. Using X (as described above) with a kernel DRM module and a
(patched?) version of xfree86 or xorg. Use xine output plugin.

2. DirectFB in conjunction with a kernel module. Use softdevice output

Is either of these preferable? I would have thought the second because
there is no overhead of running X as well but the post above says that
DirectFB wouldn't use hardware decoding. Is this still correct? Or is
DirectFB still very flakey? From what I've seen, there are about 3
different possible kernel modules, and the newest kernel patch I've
found is for 2.6.8 (and I can't find a DVB kernel patch for that old a

As I say, I have yet to try any of the above and was after some pointers
before I delve into the realms of testing different options!
