Video tearing/stuttering on high end machine

Hey guys,

Check my specs in sig, this machine should be more than capable of playing a few average quality (dvd rip) avi files in VLC player... but I get a stutter/slight tear every 3 -5 minutes when watching. What settings should I change on VLC to optimize viewing?

Any help is much appreciated!

 

I remember something about dxva but I don't know what or why. Try a different codec pack: CCCP

 

Do you have Use GPU acceleration (experimental) under Input & Codecs checked?

 

Open task manager and see what else is running. I can watch Hi-Def on my piddly Atom/Ion Revo just fine. FWIW, I use Media Player Classic HC on it.

 

with a quad, I doubt any task would cause the stutter. any chance your XT spins down ? Assuming you are playing it from the HDD, that would be the first thing I check.

 

Chimpanzee how would I check that? It seems like the most logical suggestion so far. Even without GPU acceleration my CPU should be eating those files for breakfast.

 

see if quiethdd would disable they auto spin down. google quiethdd and momentus XT should give you some more information.

 

-> I'd guess you use a rubbish codec or codec with the wrong settings...

That generally causes most of the issues.

I'd suggest using the Vista /Windows 7 Codec Pack and then play files with Windows Media Player.

-> Most of the settings are right, and you have as few codecs as needed.

 

Yea I have the win 7 codec pack and same thing happens on windows media player, even more frequently.

I don't think it is spindown either as it can happen as little as 20 seconds after opening a file. Also I can hear/feel the harddrive going.

Starting to me off lol

 

OK. Best of luck then.

 

-> OK, that's a start though the Vista One is possibly one of the best around, I'm sure it's the same for Win7.

In this case -> try changing a few settings in the appropriate codec panel and see if that helps.

 

Horizontal tearing in fast-action sequences is normally what VLC suffers from, still have not found a solution for it yet as it does it with every driver set for my ATi.

I now use the K-Lite codecs and run it all through WMP, despite what people say it is more than capable of the job - certainly no more tearing..

 

It isn't horizontal tearing, it is more of a stutter. I have been trying to use windows media player and that stutters even more frequently.

I thought I was smart and had figured it out being DPC Latency but that aint it either! Seriously lame...

 

Is Aero on or off? How many monitors are connected?

 

Aero is on. Happens if I am using just laptop monitor, or if I have it plugged into HD TV with laptop monitor turned off. I just want to watch some poor quality avi files lol!

Interestingly, playing a dvd in dvd drive is fine, no stutters whatsoever. So it is either a decoding thing, or a hard drive thing.

 

Update:

Turns out it is my other hard drive, a samsung spinpoint. This is the drive all my data is stored on. I moved the videos to my Momentus XT and they play perfectly. Now just got to figure out how to fix the other drive!

 

Daft idea... fragmentation of the file?

 

It happens on any of thousands of avi files. I'm thinking the samsung is probably spinning down.

 

Lame and quietHDD only works on your primary drive :S

 

since quiethdd actually only issue an ATA command to set the aam/apm parameter you may find another program that does the same thing(HDTune?)

the nice thing of quiethdd is that it is a tray progam so even after sleep/hibernation/resume, it would re-issue the command. So more about convenience. any program that can set the power option should work.

 

Ok, that's a start though the Vista One is possibly one of the best around, I'm sure it's the same for Win7. I have been trying to use windows media player and that stutters even more frequently.
