All of the settings you are talking about with the exception of the skip buffer are tweaks to madvr and direct 3d which don't exist in linux.
Perhaps Hendrik might comment on the efficiency of the video playback performance on linux?
You can try messing with the buffering in linux by adjusting the buffer time and period time in the Audio Options, device settings.
The defaults ar 500000 and 100000. You can bump them up keeping the same ratio to see if it makes any difference. Maybe just add a 0 to each...

I messed with those two entries by doubling the values on each. Playback still no fix.
Thanks.

At this time you simply need more cpu power to play video in linux than you do on windows.
I have no issues with playback of 1080 video even on a intel NUC as long as it's using a proper accelerated video driver.
Nouveau has known issues. If you are using that you will as well.

Are you playing your 1080P videos local or via the network?
I am not using the nouveau driver, I am using the 340.102 as listed and detected by Ubuntu.
My cpu is Intel 990 BX or X 3.87 ghz, 12 threads. with 24 gig of memory I do not remember the full specs. (Check out the specs on the cpu). You will see it is a heavy duty cpu. My Asus 2702I Windows server is not even as powerful as this.
The mobo is Assassin G1 Gigabyte. This mobo was designed for Gaming.
Everything I throw at this cpu works fine It has big muscle to do anything. At home, we watch movies over the network from various Sony/Samsung 4k tvs.
Just yesterday, my replacement USB wifi dongle arrived -- Enimax 7833UAC an RMA replacement from the company. The old 7822UAC cruised at 866 mbs, while my new wifi dongle now cruises at 1300 mbs, and my 1000 mbs
wired Ethernet adds to the performance.
With this new wifi speed, I tried to watch Guardians of the Galaxy vol 2 (ripped). Video was astonishing, but the sound did not blend with it. I have tested with default ALSA, and tried a few others.
We watched the same Guardian of Galaxy vol 2 stored on a WD hard drive attached to the Windows server, movie played fine with one or two input lags. Movie was in my opinion 100% watchable.
(I can play anything on the Windows server from my Sony tvs with no issues EXCEPT a few input lag .... 20 seconds to 35 seconds through out the course of any movie).
What I have been writing about is this.. those windows tweaks really make a big difference in performance between the windows server and the Linux server.
Now where is LAV filter, LAV audio and maybe video? Are these not Linux compatible through the use of ffmpeg?
Does ffmpeg not work with Linux?
I bet you, if someone there, you or Hendriks can find a way to add these Windows tweaks.. Buffer adjustment and the option to use Hardware Acceleration.. set to high, low, medium and or automatic, the sound issues will be eliminated.
More customers are going to want to use the Linux versions for movie watching over the server, and they are are going to be disappointed. From my point of view, If MC Linux can not play well with videos and audio over the network,
the main features of MC will be diminished.
BTW-- What is Hendrik saying or doing about this? I hope he is reading these complaints.
Around October of 2014, the Linux platform was introduced, and right from the get go, I paid and every year, I renewed my interest by paying, without even using it, now when time comes to use it, it is not working as expected.
Thanks.
George

George you must understand it's a massive task to port something as complex as MC from one platform to another and I'm sure you know that linux is not on a par with windows when it comes to things like video tweaking. On Windows the best performance from Media Center still comes from using directx even with all of the advances we've made in multiplatform video.
Now that said, the Intel NUC Dual core 1.8 ghz Id's with built in intel video using linux can playback 1080 mkvs flawlessly so you obviously have more than enough CPU.
We are working on things constantly and Hendrik reads these threads as well so you can be certain that you are being heard.
blgentry:
There's something wrong with your setups. If your windows server regularly has "input lags" something is wrong. You keep saying over and over that your Windows server won't play completely smoothly, so something is wrong. You shouldn't need to adjust all of these "tweak" settings. If you did need this, people would be complaining constantly about Windows MC Video not being smooth and there would be endless threads about how to tweak it so it was smooth.
Your statement about networking makes no sense. If you are achieving 1300 Mbit/sec, that's faster than 1 Gbit/sec wired ethernet. Wired should be SLOWER.
Perhaps we have a communications problem due to the language barrier. Or perhaps I've misunderstood the details.
I have to go back to the point of you talking about your Sony TVs. Are you trying to watch via DLNA (network) ? If so, your video card is not in the mix at all.
Or are you directly connected from your Linux MC box, via HDMI, to one TV?
