[mythtv-users] Epia 600 or 800 as backend?

I'm using EPIA-MII12000 for backend and frontend. I use a PVR-250 to 
defer mpeg encoding though. I tried using an analog WinTV PCI card, but 
the encoding was too much for that. So if you're going to use USB or PCI 
devices, first make sure they support hardware mpeg-encoding. I highly 
recommend the WinTV PVR cards. I replaced my analog card with one in 
about 5 minutes including all the software setup.

Transcoding will probably be a long and painful process for an EPIA.

EPIA has a fanless MS 8000 which is going to run a little faster than 
the 6000, but if you are hardware mpeg-encoding/decoding, I don't see 
much point in it. You could probably work fine with a 6000.

IMHO I think EPIA would make a much better frontend. Especially with 
Linux BIOS and a 4 GB compact flash card. You can avoid a hard drive 
entirely. EPIA MII6000 has a compact flash card reader. You can boot 
from it if you install a linux bios. Of course, you can also do a PXE 
boot, but that wastes valuable space replicating an OS on a hard drive 
you are probably going to use for saving your mpeg content to. It is 
also going to further consume RW I/O bandwidth to that disk.

The advantages of not having a hard drive in your frontend are obvious. 
Your frontend can run not only fanless, but super cool without a hard 
drive generating heat.

I don't know if anyone on here had much luck with the unichrome drivers, 
but mine are not working well at all. I don't even use XvMC for the mpeg 
decoding anymore. I just use libmpeg2 and my cpu has not suffered much 
from it.

The recent posts of the pundit sound pretty good to me if you're 
thinking of going small, quiet and more powerful than an EPIA. For the 
cost of an EPIA, you could get a pundit barebone which is case and 

Hope this helps you make a decision.

Best regards,
