Dear list,
I searched the Web but could not find a lot of reviews or tests about ARM based VDR systems.
The goal is to have a VDR device which consumes the „least possible“ amount of power. I heard that ARM based devices are good for this.
Does anyone on this list have any experiences using ARM based devices?
1. Since the boards are mostly small one needs to use mostly USB devices, doesn’t one? 2. Is the performance high enough to playback SDTV? It should. 3. What about HDTV?
4. Especially the Beagle Board [1][2] was covered a lot in the press. But it is not completely free, i. e. the specifications and the toolchain is not freely available, is not it [3]? Sorry, if I am wrong about this.
If there is any information I missed on the Web, please point me to it.
Thanks a lot,
Paul

I have N810 (Arm 2420 Omap) and tested the playback of sdtv with it by using the mplayer as a player which connected to VDR streamdev server. For a while the playback was good but then there were also moments where the playback or sounds get scattered.
For fun I was also planning to build the vdr-sxfe for N810 but newer finished that one... (I was not able to find prebuild xine-libs and friends for Maemo, so I would have needed to build those and couple of other dependencies first and I did not had enough time for that)

Openembedded supports beagleboard among many other targets so you can use that to build toolchain, bootable image and applications for the beagleboard. (See the angstrom distribution for example)

Well, I was not fully sure were those scatterings caused by the graphic hardware or wlan. Because for a while the screen were actually fine.
In addition that omap version is supposed to have support for davinci dsp chipset and prebuild codecs for a acceleration of various sound/picture/video formats. In reality I do not know how much those capabilities are used or how linux apps like mplayer could advantage them...

As far as I know uses the reel NetClient an ARM core but I am not shure which one and if there is an additional graphics processor onboard. As long as nobody buys this box and opens it, we won't know.

IMHO nVidia Ion is much better option. Especially for HDTV.

Did you try both options or is this just your point of view from reading the specs?
Especially for HDTV.
As far as I know the Beagle Board is supposed to play 720p without any problems. See for example [1]. The NVIDIA ION is supposed to do 1080p with VDPAU, but I think I do not need it yet.
+ The Beagle Board should use less power. - More people run and test x86 hardware. • Both use proprietary drivers.
Thanks,

Agree with you. But 720p on the Beagle Board is a hack while nVidia Ion is reality ;) In any case this is just my opinion. You can find easily case, MB with different options such external PSU, PCI extension or ready made HTPC based on nVidia Ion. Regarding the power consumption. I don't think that the difference between Ion and Beagle Board is extremely big. More efficient way to reduce energy consumption is replace all kitchen appliances to energy save ones, use thermostat to control temperature, switch off unnecessary electrical devices and use energy saving lamps :)
Thanks,
Paul

What about the Xstreamer? www.xstreamer.net 100 EUR, sounds like a good deal, now only a proper implementation of UPnP plugin for such a device?
If we're starting to talk about media players then Popcorn Hour can be used as VDR client - http://smart-home-blog.com/archives/1344

As far as I know all used components are known.
To quote from for example Wikipedia [1] it uses a TI OMAP3530 Processor, and has a Imagination Technologies PowerVR SGX 2D/3D graphics processor integrated for HD material. This is the same technology used in the Intel Poulsbo design, so the DRM drivers(?) are unfortunately proprietary.

just a small update. I posted on the Beagle Board mailing list [3] and found also a post [4] where someone had run VDR successfully on a Beagle Board but has problems with the OSD.
