1080p trailers of Batman Begins and Alexander... choppy!

post #1 of 39

Thread Starter 
Hello everyone,

I've been downloading a lot of the high definition sample clips available at Microsoft's High Definition showcase found here:

www.wmvhd.com

The most recent addition is the trailer for Batman Begins (Best movie this year so far, in my opinion) and I downloaded it witness the beauty of 1080p video. When I finally started to play the video, it ran horribly! The framerate would become choppy every few seconds. Then I viewed the 1080p trailer in full-screen mode and it was much better, but it still got choppy for a second or two at certain points in the trailer.

Now... I know the Dell i9300 is more than capable of HD video decoding. I have viewed other 1080p clips and not a single stutter! What gives with these two trailers? Also, is video processing handled entirely by the CPU? Or is the GPU aiding the process in some way? Becaues a laptop with a 1.6GHz Pentium M and a GF 6800 should be more than enough computational power to dish out 1920x1080x24 smoothly.

Is anyone else experiencing something like this? Is there a solution? Any advice, tips, recommendations are apprecated.

That is all, thank you for your time.
Chandra

Runs beautiful on mine fullscreen or windowed.
77.62 drivers
You might have a video driver issue.

Having the same problem, running the 77.72 drivers. So it definitely isn't you with a driver problem.

problems too

70.72 drivers as well -- i9300

I ran into something on Nvidia's website about "poor video playback on windows media player" -> it pointed me to some Microsoft .exe that's supposed to patch WMV 10...
It's not installing correctly, however.
(file = windowsmedia10-kb888656-x86-global-enu.exe)

Anyone know if I'm barking up the wrong tree here?

Just as I suspected. I was on battery power earlier when it wasn't running properly. I just plugged it in and tried it. Runs perfectly now. My nVidia driver settings are for max performance on battery power. I don't get it.

Speedstep was probably running the CPU at 800MHz to conserve battery power -- that would DEFINATELY cause 1080p video to lag.

I havn't even tried viewing 1080p content on battery. I have always kept my laptop plugged in for multimedia stuff.

I finally updated the video drivers to 77.72. Made a pretty big difference, but it still gets choppy at a few scenes. Namely when there is a scene transition. I'm thinking of reinstalling Media Player 10 and see what happens. Also, what is this Speedstep?

there is a fix for this: enable purevideo. This thread gives a link to the fix. http://www.notebookforums.com/showth...ht=step+liquid

and speedstep is Intel's name for their Pentium M processors throttling down to save power.

Earlier in this thread I listed this very same file that your link refers to. However, it won't let me install it. I comes back with some obscure installation error message. What gives?

You need to install another patch for DRM before you can patch the Media Player. There is a link to this other path in the thread Djembe_Rob mentioned.

Okay... I installed both patches. Rebooted the system.... and finally ran the Batman Begins trailer in 1080p again. Well... the stutter is gone, but now the video progresses at a slower rate than the audio. As a result, the audio and video become out of sync. WHAT THE F***?

Edit:
My CPU usage stays between 65-75%! I don't understand how the lag develops.

Hello! Been lurking on this forum for quite some time, but now I finally have something to contribute.

I've also been experiencing the problem with the video lagging behind the audio on my i9300 1.6 for quite some time. The WMV patches didn't help at all, so I started playing around WMP's settings today, and I found a solution that seems to eliminate the lagging.

I am using the 88.40 Go6800 drivers at the moment, but I was having the same issues any other driver version I had previously installed.

So.. To eliminate the lagginess. Start WMP and go to Tools>Options and select the Performance Tab. Click Advanced, then UNclick "Use Video Mixing Renderer." Click ok, then Apply the changes and try watching the trailer again. That should stop the lagginess.

But.. I am not completely certain on this, but I THINK this disables hardware decoding. Because you'll notice that the slider bar in the Performance tab that asks for the level of decoding is now grayed out.. I did notice a couple frames dropping during the Batman Begins trailer, and CPU usage frequently spiked at 100%... But, the video doesn't lag behind the audio anymore.. So I guess it's a trade-off... I'd rather lose a couple frames and keep the audio in synch with the video.

But, on the other hand, we shouldn't be having this issue in the first place.. And I'd like to solve it without potentially disabling hardware decoding..

Another possible culprit is data rate. How large is the trailer on disk and how long is it? If the # of MB that has to be played per second is high, it may be that the hard drive is not able to keep up. Some people can play it correctly, some can't, so if it is data rate related you'll want to a) defrag the disk, and b) check if the ones that can play it smoothly have 7200 rpm drives and the others do not.

I see what you mean, but I'm not sure I completely agree. The Batman begins trailer is 164 mb, and is 143 seconds long.. That would give you about a data rate of 1.2 mb/second.. Any hdd built today should be able to easily handle that.

Another reason I don't agree with that is that WMP is supposed to drop frames to keep the Audio and Video synched, but for some reason, it's not. If the hdd couldn't handle the data rate, the video would look like a slide show.. It wouldn't just be playing slowly.

Wow... ov3n... that did the trick. I still get slight stutter at a few instances (namely at screne transitions), but it's not bad at all. Thanks man.

I'm okay with how it is working now. But if anyone knows how to completely eliminate the stuttering... please post here. Your advice/recommendations are greatly appreciated.

Major thanks ov3n.

Edit:
My preferred decoder is always set to software! WTF? Is there a way I can set it to hardware? No, enabling video mixing renderer does not allow me to change this.

There is a basic truth here that needs to be stated. a 9300 simply will not perform as an XPS GEN2. I ran both the Batman and the
Alexander clips at original resolution and full screen. Perfection.......(beautiful clips and thanks for the URL). I'm running XG 80.40 drivers, and I have a 2.00 Ghz processor with 100 GB 7200 rpm drive. I wanted maximum performance in all situations, and I paid the premium to get it. I would agree with those who say the premium may not be worth it, bang for the buck.

Dare I generalize? The complaints seem to come from the 9300 owners. No probs with XPS Gen2. I'm running 5172 3dMark05 un-OC'd, and high 5300's with auto overclocking/RivaTuner (although I confess I haven't found the trick to achieve overclocking that stays that way beyond a reboot. I go back to 450 and 1.06.

It may be that your 9300 just can't get there.

Perhaps not, seeing as only 4 posters in this thread report having i9300s, and 2 of them have said they've resolved the problem.

Well, not from me.... Every one of those clips run fine on my maxed-out top-of-the-line i9300. 2 GB /2 Ghz /7200 RPM with 80.40 drivers.

Yeah, you're right, that data rate shouldn't stress the HD much.

I have noticed that when running at 2266 mhz the clip uses up to 70% of the availible cpu. Could someone with a 1.6 post what their cpu usage is?
