HP & 1080P MKV file playback

I have an HP HDX 16T with a P8400 at 2.26GHz and 4GB ram.
The video is nVidia 9600M GT driver 7.15.11.7622 with 512 dedicated
memory. The TV is a Sony 46" Bravia KDL46V2500 1080P LCD connected
via HDMI.

I have an MKV file that is 1080P & 8.4GB in size that will not play correctly.
The video is choppy and the audio out of sync.

I downloaded the latest versions of the following players/codecs.

KM Player
BS Player
VLC Player
CoreAVC
SM Player

All of these exhibit the behavior, some not as bad but all have an issue
playing the files. In fact it seems to be any 1080P file that gives me issues.
All of my 720P play fine with any of the players listed above.


Is my hardware not up to the task? I know HP offered a blueray drive as
an option so surely this computer should be able to play 1080P....

Any thoughts/suggestions welcomed.

 

Try installing Haali Media Splitter and then use VLC or MPC to run the mkv....

Also see if Super runs it fine in its integrated player.

 

that is ridiculous. your hardware should handle 1080p just fine. Try getting the latest gpu drivers and see if that helps.

 

Definitely not your h/w. On my HTPC, I have a AMD4850e CPU with Gigabyte 780g mobo (onboard Radoen ATI3200) and I can run all 720/1080p MKVs fine. This is with a $70 CPU and a $70 mobo!!

I'm using Windows Media Classic with Haali Splitter, CoreAVS and FFSHow. With FFDShow, I get stuttering but with CoreAVC, I can play anything butterly smooth with CPU throttling around 45%-50% (with Prince Caspian 1080p rip which is a 13G file). The key thing is such software doesn't allow h/w acceleration and hence why the CPU gets too much load. In my opinion, CoreAVS is probably the best software codec to handle 1080p MKV's.

Also, installing too many codecs are cause conflicts.

 

Codecs cause conflicts when two or more decoders are assigned to playback the same fourcc/format, otherwise not. I've numerous codecs and stuff, no conflicts -.-

For the average user, K-Lite Standard (or Full) Codec Pack is good, as it has all the necessary decoders to playback the common video file formats.

 

Thanks for the replies...

I have Haali installed, CoreAVC updated me to the latest version.
What did you mean by "see if Super runs it fine in its integrated player"?
Are you suggesting using a player to downgrade to 720P?

HP's latest nVidia driver is 7.15.11.7904 A, I will try installing it now...

I was wondering about the codec conflict myself but I can play any and all
AV files just not 1080P ones....so I tend to discount the codec conflict theory. How can I optimize CoreAVC? It isn't a player, but rather a codec for a player like KM, is that correct?

 

does that file play back on other hardware in sync and smooth ? Your hardware is better than needed

 

Do other video formats play at 1080p?

It could be a HDMI limit in the cable its self.

 

I can play that file back on the desktop I built but it is a gaming rig
and has much much better hardware.

I also have another 1080P movie in MKV that won't play on my HP.

I don't tend to think so, I have two of the same HDMI cables, one connecting
the HP, another connecting a desktop, the desktop will play the file.

At first I thought it was the file but two files are doing the same thing, audio
out od sync and video is choppy.

 

The newest HP drivers made no improvement.

Would I really see a gain with Laptop2go drivers over the HP
for this purpose? I always figured Laptop2go drivers were optimized
for OC'd GPU's and gaming.

I did notice one of the CPU cores hitting 94% and the other 34%
while playing the video file, they seem high from what others have
stated. Any idea why?

 

what are the complete file specs of the MKV? the content may have been poorly encoded. alternatively, simply purchase the Blu-ray or HD-DVD from which the content was pirated.

 

WoW! A very insightful post! however your attempt to "guess" the file
content and source is incorrect. The file is "The Immortal Voyage of Captain Drake" which aired on Sci-Fi channel and was available for anyone with a Tivo or other such device to record.

Seeing as how your incapable of providing technical assistance, please
keep your useless prattle to the one person listening----you.

 

I can sympathise with you here, it should work.
I have a 8600M GS on my DV9774, latest drivers from nvidia and audio driver at this time. I only have VLC and Windows Media Player. So using VLC for 720p and 1080p to my 42" Panasonic plasma via a cheap 12' HDMI cable and I have no trouble.

I have never ever downloaded any "codec pack" on to my clean Vista 32bit install last summer other than I downloaded Xvid from their site so I can play Xvid files. VLC is whatever it comes with.

I hear what you say about the same content works from your other computer but not from the laptop...

Bit simple....but can you uninstall and clean off all the added on media players and codecs and start again with one? Sounds like a conflict as obviously your hardware is fully capable. I'm sure if it was hardware at fault you would see way more problems elsewhere. Gotta be something in the software.

Good luck with that...

 

I just downloaded a bunch of 1080P movie samples to see if i could be any help, even though i watch BD's all the time on mine.

Transporter 3, Taken, 7LBs, Roving Mars, and Matrix 1.

All 1080P .MKV's. I have nothing but VLC .8.6i installed, never anything else installed. I have a clean install of vista, T9400, 3GB, and the 9600m GT.

i know this isnt the most exciting grab i could've taken, but thats what was happening at the moment.

All samples played silky smooth, just like my BD's. Could be a conflict somewhere with your codecs.

And yes, i did try hooking it up to my tv as well, 1080P. Same deal. silky smooth, same cpu usage.

 

BTW, im using the factory 176.22 Nvidia driver

 

Thanks to everyone who posted....you guys gave me an idea to
examine the player settings, I dabbled with KM Player as I use it
the most (My HP remote will work with that program) and found
that by going into "Filters>AC3 Filter for AC3>Main>Output Format
[change this field to Dolby Surround/Prologic @ PCM 16bit].

Video and audio are in sync and play smoothly.

Any idea why this would be necessary? and will I have to change
it back and forth for other files?

------------------------------------------------------------------------
Edit:

I spoke too soon.

The audio goes out of sync after 10 minutes or if I fast forward.

UGH!!!

 

Are you plugging your laptop in while you are using HDMI to your tv? Perhaps you are in power saving mode so your hardware performance is being throttled.

Give that a quick check

 

I think I may have resolved it.

I changed the KM Players settings to use the external CoreAVC H264
decoder. The movie played all the way thru no problems and I can
jump forward and then back again all the while it remains in sync.

I just need more 1080P files to test so I can be 100% sure.

 

Glad you have fixed it.
Maybe I should try KM since the remote works in it.

 

You have to edit the KM Player preset Global Control list for the remote
to work and only the bigger HP remote will work, not the credit card remote.

On the other hand, try one called BS Player, both remotes work naively.

 

had you posted the file specs of the MKV anyone would have been able to suggest the appropriate codec within *minutes* . all you achieved by tossing off unnecessary drama is further frustration (as evidenced in the above posts) and unnecessary trial-and-error

 

Did you leave your corner again?

Don't make me call the nice Doctors to the house.

Put your dunsel cap back on and sit quietly in the corner.
