Looks cool, a couple of questions pop to mind for me...

They say they tested mpeg4 (xvid/divx) that takes advantage of the accelerator, I wonder if that would work in mythtv/mplayer/xine or was somehow engineered in the epios that they were running?

Would this work "out of the box" with minimyth?

Not at this time.

The Epia M series motherboards use the CLE266 for hardware accelarated MPEG2. The EPIA SP series motherboards use the CN400 for hardware accelarated MPEG2 and MPEG4.

MiniMyth 0.17 uses the Open Source Unichrome drivers. While these drivers have support for the CLE266, they do not have support for the CN400. However, the developers are working on CN400 support. There is a working version of CN400 MPEG2, but my understanding is that CN400 MPEG4 is further out.

Apparently Via recently released the source code for their CLE266 and CN400 drivers. Depending on the licensing and the readablility of the source code, this may help the Unichrome driver developers with their CN400 driver development.

I have a Commell LV-667D, which has the CN400, because it has DVI output and should support HDTV resolutions. Therefore, once the Unichrome drivers add CN400 support, I will upgrade MiniMyth to use the new drivers.

One thing I'm not clear on: When there is driver support, should this board be able to decode an HDTV stream (1920x1080i)?

Is anybody here watching HDTV? What are you using? I've been looking at the Roku's but I don't want to have to port the myth frontend.

According to Ivor, he is able to play full 1920x1080 HDTV (with debugging on and the CPU at 95%). However, I do not know which board he is using: Commell LV-667 or Via EPIA SP13000.

What drivers does epios use for decoding it then? The review says they tested the acceleration, but then also said that windows did not support the acceleration. SO it had to be a non-windows video driver...

I suspect that it uses the Via supplied Linux driver. It is my understanding that the Open Source Unichrome driver and the Via driver provide different interfaces. Therefore, using MythTV, MPlayer or Xine with the Via driver would require a version of MythTV, MPlayer or Xine that has been modified to work with the Via driver.

Have you done this yet? I would like to be able to watch my HD recordings on a diskless fronted. :)

Actually Pablo wrote that. I have no HD or compatible board :(

No, I never did. There is sill no DVI support as far as I can tell. Right now, I have been playing with an NVidia based solution that has DVI support. That is why the GAR MiniMyth build system has support for one non-EPIA board.
