Yes, one main problem resolved.
I am really enjoying this new build now. My movies splash to the screen with speed, as if the image is going to knock you down. At times, opening screens look like 3D and screen is super fast. I mean "FAST"
Thanks to "my" CEO.
Take care.
George

Greetings:
I think I found a cause or causes relating to skipping, buffering etc.
As I still have my Windows server up on 23.0.41, I compared the settings and options available to the Linux versions:
Before I go further, I have ripped and re-ripped again some of my mkvs to be sure I do not have some bad rips. I also have on the Windows server, a Western Digital drive with movies and concerts left for testing.
There are some missing options on the Linux versions.:
The Windows version has: Audio:
Device Settings:- Channels- Buffering.
Under buffering there is a slider from left to right that has to do with skipping, which reads "more skip resistant. From the left sides a slider that goes up showing more responsive. 0.05 seconds.
Under Video-- there is hardware acceleration video decoding.
General: Video card.. Hardware accelerated graphics.. automatic, highest quality low medium., then custom 6x full screen anti-aliasing.
On the windows server, I was able to get Celine Dion- A new day, Lionel Richie- Live in Paris , and Bee Gee One night only to play for about 20 minutes each with no skipping. This was due to the fact that I moved the slider almost to the end of the gradient.
Before this, without moving the slider up, the windows server playback over the network was just like the Linux server.
Then going back to the Linux server, I was unable to watch any of these concerts blu ray and movies
Today, I ripped Guardian of Galaxy vol 2 Blu ray, put it on the Windows server, it played nicely with a few audio skipping, but the movie was watchable. The server has an AMD card, a mediocre graphic card and the Core I7 is not as powerful as the Linux box.
Also on the Windows server, movies like Prometheus, Alien Covenant with heavy graphics played nicely with no audio drop out for almost 30 minutes. I noticed Prometheus and Covenant would break or video drawing slowly on the screen, before, then all just become smooth and pleasing to watch... All these now possible by adjusting the buffer menu options, which are lacking under Linux.
Also I am wondering if 3D can be played under current issues relating to audio skipping. I have not tried 3D playback since the resurgence of these issues.
Under Windows, we have menu or options to tweak 3D.
I will appreciate if you take some time to review the codes, to see if these missing options if added will fix or
improve the overall enjoyment.
Thanks.
George

George, the linux version doesn't have as many bells and whistles as the windows version.
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...

Glad to hear from you.
I see these values on Device settings for audio. I have no idea what value to use.
Is there anyway for Mr "H" to tweak it for Linux?
Also in Windows, there is a place for Hardware Acceleration Medium fast and high for graphics cards.
If video is going to play nice with audio, there got to be a way for MC to play both smoothly.
Now, it is not working at all. Audio is really messed up with video.
Please let Mr. "H" know that I am worried about these issues. A library with more than 1500 mkv movies not playable under linux. When I bump the values up, I will let you know of the results.
Another minor issue: Someone just reported Theaterview freezing, locking under windows. Under Linux, it is doing the same also. Start up with theater vew, it goes to audio, though not asked to go to audo, then getting out is problematic.
I have to use ctrl alt del keys to escape.
Thanks.
George
