I am having problems playing 1080p mp4 videos on my computer, and I can't figure out what the cause might be. I have not yet tested other video formats yet, but plan to in the next couple of days.
This is my machine:
OS: Vista x64
CPU: AMD Phenom II X2 - 3.1 GHz Dual Core
Video Card: HD 5770 - 1GB
Memory: 8GB RAM
Disk Drive: Western Digital - 2TB w/ 64MB Cache - SATA 3.0 Gb/s
...WHAT I HAVE TRIED SO FAR...
FIRST TRY: When I first tried playing the video, I was playing it on Windows Media Player (latest version, no updates available) using the K Lite Codec pack. The video had some visual artifacting and it kept lagging and skipping (audio seemed to play forward at a regular speed while the video played back in a disjointed and slow manner). Looking at system performance in task manager showed that the CPU was pegging, with Windows Media Player using up as much of the CPU as it could (the rest being used by other open apps, of which there were only a few). Memory usage wasn't very high, but the CPU was bouncing around between 80% and 90+% usage. Even after I tried closing the other apps, the playback remained the same.
SECOND TRY: I uninstalled K Lite and installed VLC. This was worse. The CPU pegged and the video basically froze, playing back audio but only intermittent, broken pictures that looked like negatives.
THIRD TRY: I uninstalled VLC and installed DivX. Same as VLC.
FOURTH TRY: I uninstalled DivX and installed haali media splitter and ffdshow. Then I tried running it in Windows Media Player again (since that was the player that gave me the best performance so far). It seemed to be the same as the first attempt: minor visual artifacting with slow and jerky playback.
I would think my machine would be enough to run 1080p videos, but something is clearly not working right. Does anyone have
any suggestions? Thanks!

CODEC packs on Vista and Win7 are a bad idea and most times they don't uninstall cleanly. Go to Microsoft Fixit and run the Media player fix. I've had worse issues than you; playing media files in Win7 would lock up the PC. WMP is the only player that works, but I had to update the video card driver. A player that doesn't need external CODECs (VLC and MPCHC) should work too (not so well for me though).
Get the lastest driver (from AMD/ATI), or get it from the card manufacturer.
And check out this post. -

Thank you all for your replies. I will try some of these suggestions out when I get home from work, and I will post my results.
jagabo, this is a great question, and I have no idea what the frame rate is. I googled for a way to check this, and found that "GSpot" might tell me. Is that the way you would suggest finding the frame rate?
nic2k4, you say that CODEC packs are a bad idea on Vista and Win7, but WMP won't play the mp4 file without a CODEC install. Can you tell me more about why they are bad, or how to get WMP to play an mp4 file without a CODEC?Last edited by juarez; 10th Jul 2012 at 18:58. Reason: Added a question for nic2k4

Not all h.264 features are supported by DXVA (Microsoft's hardware video decoding application interface). Players that use DXVA may choke on videos that exceed DXVA specs.

Try mediainfo to inspect the files. We need details about what kind of video's you are trying to play. Because yes some files plays on all computers very hard like jagabo said.
In case it should have been able to play,
If you give VLC another try, here is a topic about how getting better performance playing HD files. Look at last page too about enabling GPU acceleration
http://forum.videolan.org/viewtopic.php?f=2&t=42328
But your computer specs are nice. I never had problems playing 1080p in VLC or with MPC + CCCP codecs pack.
Maybe you need to reinstall.Last edited by Abas-Avara; 11th Jul 2012 at 08:47.

Thanks again for all the help, everyone.
I used MediaInfo to check the file out. Maximum frame rate of 30, video encoded with AVC. Before cleaning anything out and starting over, I tried VLC again, enabling hardware acceleration. That was better than the first attempt with VLC, but still not great. Then I tried MPC, and found that DXVA was already enabled.
MediaInfo sent me to the QuickTime download page for a player to play the file, and for the driver. So I downloaded QuickTime and tried that. It was okay, but still not great.
THEN, I googled for players that play AVC, and Splash Lite came up. So I finally tried that (remembering that Steve had suggested that), and it was perfect. Just no hassle at all. Like a dream.
One day, when I get some time, I would love to go back and try more of these suggestions; try and get some of these other players to play the video better. I clearly don't understand this topic that well, but all of your help was much appreciated and got me where I wanted to go. Many thanks! -
