Thank you. I indeed missed that vdr + softhddevice + libvdpau-sunxi
exist. I will take a look at it. When I succeed in creating a functional
VDR box with it, I'll add it to these howtos:

I suppose you missed that vdr + softhddevice libvdpau-sunxi is working
on A10/A20 hardware already and makes these devices nice fanless
energy saving vdr clients. Including deinterlacing.
Actually cedarX hw decoding was another question I forgot in my
previous post. I've read that it's working in linux but I didn't know
if any output devices supported it (yet)?. Was hoping softhddevice
does, or would if I sent Johns an A20. :)
So first, forget the cedarx binaries and take a look at
There is a libvdpau backend driver for A10/A20 devices, that supports
hardwares accelerated video decoding and presentation.
With johns' help we tried to improve that piece of code in the last
few weeks and have now something, that is working very well imho.
But it's not finished yet and not all vdpau functions are implemented.
Because of the way libvdpau-sunxi uses the hardware, there are still
some limitations, especially when working in windowed mode. But it's
quite good useable.
You may give it a try: https://github.com/rellla/libvdpau-sunxi
There are already a few threads and howtos in the german vdr-portal.de
and in vdr-wiki.de iirc.
It also should be no problem to make a vdr server out of one of these
boxes. It's nothing else than linux on an arm box. I recommend to take
a device, that has sata and put your rootfs there instead of sd card
or nand. And maybe you will have some limitations due to the bandwidth
(usb etc.) as with the other arm boxes as well.
I have used the olimex A20-OLinuXino-MICRO-4GB with 3 DVB-T receivers
all connected to one USB port of the A20 via a hub. my receivers can't
filter the data, therefore the entire datastream is sent to the A20.
When recording 3 TV shows concurrently, this is 24MB/s (192Mb/s) of
data. I have almost never seen glitches in the recorded shows.
When used with samba (and large files), the A20 delivered 11MB/s from
the SATA HD to the 100Mb NIC.
I can say both the USB and the SATA buses are quite capable.
