[mythtv-users] Low end NUC as backend/frontend?

Ok,

Here is my final Verdict on the Haswell NUC Core i3 Model # D34010WYKH

I built Myth .27 fixes from source (git pull tonight) and I can confirm
that the new build does in fact get rid of 99% of the stutter with the
video when the EPG is on the screen with 1 caveat:
I have to be running either VAAPI with its Crappy Deinterlacing Support OR
OpenGL with a software or Hardware non 2x Deinterlacer. If I run any 2x
deinterlacer the video gets Jerky once the OSD or EPG comes up.

Other than that I have been able to get the Nuvoton CIR receiver to work
with IR-Keytable and LIRC and get the Media Center RC6 protocol remote to
work great.

If I could just run OpenGL with a HW 2x Deinterlacer I think this would be
a GREAT fronted.. As is, I think I will have to live with a bit worse
deinterlacing and run it on a secondary TV.

While Typing this I have discovered another interesting issue... I get Video
Stutter in the EPG if its a 720p Source Chanel (ESPN) but I don't with
1080i source TV Channels... Maybe a difference in 30fps video vs 60fps video?

Ok... Was looking around on TRAC and found this:
http://code.mythtv.org/trac/changeset/1b16c65f465588a8991b730fb23ef0d1c61ed181/mythtv

This sounds EXACTLY like my issue, and I am using the MythTV package from
Xubuntu Repo's... Which I *think* may have been built before this was added
to .27 fixes.

So I am going to manually build .27 on the NUC and and see if it is any
better!

I will post what I find!
