Has anybody had a problem of TFT going out of Sync while playing a video file

[jaykishankrk]

Hi all,

Rig in my Sig.

i don't know the reason why my system gets hanged or makes the TFT go out of Sync whenever i try to play a video file. its not a sudden effect, it plays for some amount of time and then it happens, i have checked the temps of my processor and graphics card and they seem normal to me at 52core for proc and 55-60 for my VGA. i can play games uninterrupted for as long as i wish nothing seems to happen while doing this but only with movies there exists the problem.

has anybody witnessed this before ??

If it's just movies it could be a codec problem. What codec pack do you have?

 

[jaykishankrk]

i have Klite codec pack...
and even tried to install divx too...

but sometimes it even gets hanged and i wonder why??

my OC is orthos 12hours stable!!

latest Xtreme geforce driver for 7950 Gt by tweaksrus

What CPU? Prime95 (orthos?) mostly only checks FPU stability, video decoding puts more stress on integer units, and at least Netburst P4s are more sensitive to integer. Meaning your OC could still be unstable.

What do you mean goes out of sync? Tearing?

CPU: E6300.

my OC is perfectly stable, playing a DVD should not stress CPU right??

i dont think its OC problem, it might be that i had divx and klite codec both installed, i did remove both and installed new version of Klite mega codec pack. it seems to be working fine in XP. In vista it doesnt play an HD video(crysis demo video) it gets stuck nothing moves??

TFT just displays out of sync with say 75 horizontal and 73 vertical(vague figures though) and sometimes it gets stuck and there after hangs.

Installing codecs are like getting a bad vd. Evening un-installing doesn't get rid of it.

so what else u suggest me to do, i need to run videos of different formats. Klite mega codec supports almost all formats which made me to install the same. if u have any other codec package then please suggest me, it will be very helpful (i would be very happy with a non buggy codec).

guys please help!! I HAVE RAN OUT OF IDEAS.

Let's get this straight. Your monitor shows "out of range" during video play back, as in it is being sent a faulty video signal?

Alright, well first of all: codecs can not change the frequency of your monitor. They are simply libraries containing decoding functions.

What can are various libraries that drive video playback, like the video mixing renderer. I would suggest forcing DirectX to 60 Hz with dxdiag/"More Help" tab. Also set whatever video play you're using to VMR or DirectX.

If this is happening in windowed mode, it could indicate a STOP error (driver crash). Don't assume it has anything to do with your monitor. Your video driver crashed, stopping the signal to the monitor. Or, your audio driver crashed, in turn killing your video driver. Any driver that crashes will cause a complete system halt.

Is audio still playing after it goes "out of range"? If not, are there any weird effects like audio repeating? What I'm trying to get at, is if your system is actually still up when this happens. It's possible just the function that drives your monitor in the video driver has a bug in it, not necessarily causing a complete halt. I would also check your event log, disable 'auto restart on STOP error', and provide any core dumps associated with the problem.

Ans: you are absolutely right on that.

I didnt know it the way you are describing.. well i learnt something then.

Well that is a bit alien to me, i have never tried those things before. My TFT is running at 75 mhz and nothing else i know better.

Your video driver crashed, stopping the signal to the monitor. Or, your audio driver crashed, in turn killing your video driver. Any driver that crashes will cause a complete system halt.

it happens in both window and Full screen mode.

you are right on the button man, i think u r reading my mind as well as my systems

this is what is happening all the time... especially that audio repeating thing causing a weird stretched noise of the original audio and the system responds for 10 seconds or so and then it freezes.

well i think u got my problem, if u need any further clarification please tell me so..
i am ready to give any details regarding this.

thank u very very much.

 

[xtknight]

Just make sure you give all the details you possibly can. I'm only psychic on my lucky days.

You are definitely getting a driver crash if the audio is repeating. Basically what is happening is the audio buffer is not being updated so it plays the same thing over and over (sometimes accompanied by a sharp distortion sound).

You will need to grab any crash dumps you have available. Go to start menu run, type this exactly and click OK:

"%SystemRoot%\Minidump"

See if there any .dmp files. If there are, I recommend zipping the latest one (or perhaps even all of them) and uploading it somewhere.

there are about 16 dumps that i found, searching for a place to upload.....

i can mail u, if u can PM me with ur mail ID, Trust me i wont disclose it to public

Well, it looks like your last dump was from 01-08-07 so it's likely unrelated to this problem. But most of the dumps seem to be related to ntfs.sys (maybe IDE controller problem?) or sptd.sys (Alcohol 120/Daemon Tools/etc).

The best you can do is limit the problem. You should try another media player, like:

http://oss.netfarm.it/mplayer/gui/mplayer-gui-rtm-svn-22351.7z

This one is quite significantly different than most in that it uses its own decoding functions and display libraries. And by all means disable every OC you have on your computer. OC test tools only test certain parts whereas this video might be stressing another part of your PC in a specific way that causes it to crash.

1-8-07 is pretty old log, i can tell you one thing for sure, i was using PoweISO tool to mount the image of the movie and used media player classic to play the .dat file. my recent crash was on yesterday and that too so many times.


i have rolled back to basic forceware driver from the installed tweakrus driver xtreame97.92.
i have not come across any problem until now, i am playing the same movie right now. i will keep u updated, the player u suggested needs a clean install otherwise it crashes for anything i touch during play

 

[jaykishankrk]

no respite for me, still the same OLD Fvcking problem... as you said i should take off my OC and check it out... thats the only way i think...

 

[xtknight]

I know it sucks taking your OC off, but stock E6300 isn't that bad is it?

..was your GPU o/c'd also?

i havent touched my GPU at all, its harsh to bring it to stock when u know it works great starting from Games to all other applications and sucks only while playing video..

i really dont understand this fvcking problem... how can i play games for so long without a hitch in any way and cannot play movie file for 30 minutes?? :|

i have one crazy system i tell u... it really sucks to go back to stock, its hard to feel the low performance isntit??

I'll have to be honest and say it's probably not the OC. But when doing controlled experiments/tests/diagnosis, there is no "probably". You eliminate the factors to the best of your ability.

I'm not sure how you could feel 3.0GHz->1.86 GHz when the processor already processes everything decent-sized in <1 ms. For general usage, of course. Let's get the problem solved before you do any gaming/whatever. I can't see how it's a big deal for debugging, after all haven't you ever used a 66 MHz Packard Bell when your main PC wasn't working? The only thing you are delaying by leaving the OC on is the remedy of the problem.

So, with mplayer-gui, you said just loading a file and clicking play causes a crash? I think it may be related to PowerISO. Play a local file (one on your HD) with mplayer-gui?

Everything I've seen so far points this problem to a software/driver one so don't worry too much yet. What OS? And have you applied all dual-core patches, etc for it?

on that note its time to get back to stock

will experiment with the same setup and let u know the consequences!!

i dont know whether i can catch the error within a minute or two but if i found the system to be ok for the full movie length then i would consider it a success and something wrong with the OC otherwise i am happy that my OC is safe

OS : windows XP service pack 2 and the thing about dual core patches i have not heard of one

I think that's the proper one. Again, I doubt it's the problem but it's worth a shot.
