MY HARDWARE:
ZOTAC IONITX-A-E, 2GB DDR, 2x 2TB SATA

Before the update to XBMC 9.11 (linux) I had no problems with playback.

Yesterday, I clean install XBMC Live (official) and radomly frames lost (audio and video) just appeared. In one 2h video I've got 15-20 slowdowns with no sound (1-2s per one).

I play movies from the internal HDD (SATA).

I try newest nvidia drivers and Perfect 24Hz script, nothing change.
This issue is radomly and also applies SD material like dvix/xvid/mov - not only HD.

How I can prepare debug log?? I will pause soon after the onset of issue. If it helps?

as you can see from my tag im running dharma and have done it for some time. I have no problems with framedrops. I'm not ruling out
bugs in xbmc but other setup/config troubles is more likely.

Again try the live cd without any tweaking of settings...

Did that, same problem, on both PC's. I'm not ruling out setup/config troubles in my set up, but when this occurs to two different PC's, bugs in XBMC (or nvidia drivers or a combination thereof) is more likely. Especially if you think that I'm not alone in this. There are numerous people posting about fresh Dharma installs resulting in framedrops/stutter/slomo's etc. And those are only the people that took the trouble to actually post about it.

So does playing movies directly from internal hdd work for you guys ?
Im using smb with no problems... Might be some network problems

no, same deal. It doesn't matter whether I play movies from the internal HDD itself, over SMB or over NFS, or using MHDDFS to combine several drives into one "view" and share that over either SMB or NFS. It all results in the same framedropping. I didn't suspect the network to be a problem to begin with as it's a full gigabit network with all cat6 cabling and quality switches and routers. Practically no latency and very high bandwidth. When copying files for instance the network utilization is minimal and speeds are as if you're copying from one internal HDD to another internal HDD. Only MHDDFS is slower as it caps out at about 30MB per second, but it also does that when it's local (from MHDFFS of local HDD's to a single local HDD) as it's a fuse module.

But to make a long story short, network or local files, no difference. Still framedrops. XBMC Live CD, no difference. Still framedrops There is something that's simply not right with the combination of XBMC Dharma, NVidia GF210 (or it's driver) and perhaps even elements of ubuntu 10.04 might be a part of the "bad combination". I don't know.

Anyone?

The logs are full of these:

What does it mean? Is this causing the framedropping/stutter that we're experiencing? Is there a way to prevent this?

[Ronner]

*BUMP*

Still having this problem after months. Is there a solution to this by now?

[Devaron]

It's still a problem afaik. I also have this problem. I have spend quite some time figuring this out, but while i can bring the number of framedrops/stutters back to a minimum it's not completely gone.
Have you tried this yet?

[Ronner]

HAH, if I tried that? about a million times in a million different ways.

Nothing helps mate, and I'm beginning to suspect that it has nothing much to do with XBMC, but more to do with a certain combination of kernel, nvidia-drivers and x11.

I'm waiting on XBMC being available in a ppa for 11.04 and I'll try some stuff again.

Totally annoying that anything I watch has this weird skip/stutter/slomo effect every now and then, and I'm pretty sure it's not the hardware as it's on two different more than capable PC's.

I solved my video performance problems by disabling the powermizer featur... the gpu runs at full speed everytime but the video playback is perfect...

[mr.sparkle]

disabling the powermizer feature

how do you do that from command line?

[john.cord]

Like in this Thread

http://forum.xbmc.org/showthread.php?tid=84724&page=2

with the Option

Code:

Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerLevel=0x1; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1

in the xorg.conf under the Device Section

More infos about the Settings --> http://tutanhamon.com.ua/technovodstvo/N...IX-driver/

Keeps the GPU allways at max Speed, more heat but perfect playback. I discovered that this bug is very old and caused by the nvidia drivers. Crazy that they dont fixed it in the meantime...

[Devaron]

Did john.cord's advise help?

For me, JumJum's "howto" helped reduce the amount of judder from once every 5 secs to once every 20 secs or so. After reading a LOT of posts in a LOT of threads in a LOT of forums i learned that the refresh information can be added as arguments to the ModeLines in xorg.conf (I'm new at Linux).

When i tried that, the judder reduced to about once every minute!

I can't remember where i got that information, but i will try to find it again for you. Tomorrow, because i'm off to bed after this...

Oh and sorry for my English... It's not my native language.

...Plus it's late...

[Devaron]

I found the links i used to reduce my video "stuttering" issues. I hope they will help you further.
