Test it out ... no need to invest money to get another lossy format running, when AC3 is good enough.

First post - thanks to everyone who has provided such great information on this forum. With recent patches (BIOS for power issues, beta 7 for IR module) Haswell NUCs are almost a "just works out of box" home theatre experience.
The one problem I cannot overcome, though, is pixelation/freezes with live TV using my PCTV 290e nanostick tuner. I get this with all the Openelec 3.95 betas. I notice similar reports here (around post 2743) and elsewhere (Openelec forums) but no potential fixes. The one conflicting report is from trsqr (post 2741) who says everything is rock solid stable since beta 3. Does anyone else have stable live TV on their Haswell NUCs? If so, perhaps you could report hardware, software and settings, which might help pinpoint the problems some of us are experiencing. My setup is:
nuc d54250wyk
290e plugged into USB 3.0 socket (this might be significant, a 2.0 socket would use different kernel modules)
openelec all betas with tvheadend
pixelation and occasional freezing, especially on HD channels, especially when there are graphics on screen (including xbmc menus)

Check dmesg for further info - I think it's a driver bug. Can you try another card?

Thanks fritsch for quick reply - I am happy to try lots of things but hoped to narrow down possibilities (especially given trsqr's "it all works" post) before I dive in! One thing I cannot easily try is a different tuner though. I thought I would start by trying a February 2014 nightly of openelec (see post 2613) and, if that works, see if I can narrow it down to a particular openelec git commit. I will of course look at dmesg to see if there's anything interesting. The other thing I could easily try is ubuntu 14.04 + vlc instead of openelec + tvheadened. Anything else you would suggest?

can you make a video of the pixelation?
i also use a nuc (d34010) and a pctv tuner(461e) and i suffer from artifacts on HD channels. Maybe it's a similar problem.
when i use dvbsky s960 as tv tuner, it's working fine.

I am sure it's the same pixelation as you and others have reported - varies between slight blockiness and occasional red horizontal bands, lasts a few seconds until the next keyframe. When it freezes (rare) it's exactly as described in Openelec issue 3064 here (audio keeps playing):
https://github.com/OpenELEC/OpenELEC.tv/issues/3064
The problems are 100% reproducible if I record the TV program - i.e. the problems always happen at the same point during playback, producing the same artifacts.

It depends what kind of material you have. With good speakers and good av receiver you hear difference with dts, sound is clearly spacious and better rather Dolby digital.
Of course you have also to consider the quality of the audio encoding.

There is a Patch in Beta7 - http://openelec.tv/forum/120-news-announ...7-released
Quote:linux: add patch to enable Nuvoton CIR driver on probing, see https://patchwork.linuxtv.org/patch/22339
Maybe the fix for enabling CIR by autostart.sh isn't needed any more.
Can anybody confirm whether this is the case? In other words can I remove the autostart.sh script now that I have installed OpenElec 4.0 with XBMC RC1?
2014-04-30, 13:36
nope. it did not work for me when i tested it some days ago in the nightly build.

Same issue on Rpi , so maybe not a nuc issue ??

Confirming that the beta bios fixes the shutdown/WOL/suspend issues. Shutdown works fine with WOL enabled, suspend works fine and stays suspended, no unwanted wakeups or crashes.

Hi,
Where did you get the beta bios from?
Can't find it on Intel's support website...

Anybody know which kernel version will include this patch?
