Slow HD | 1080p Playback | troubleshooting | Fix

Recently I have been having issue with my Aspire-8920 laptop whenever I try to play 720p or 1080p movies I experience ver slow HD playback, either very choppy in VLC or its in slow motion in MPlayer Classic, I tried several method to trouble shoot which I would talk about in this how to, this does not guarantee that it will solve your slow HD playback issue however the goal of this how to is to identify whether your computer doesn't have enough resources that is causing slow HD playback, or its just a configuration problem that is causing slow HD playback, this how to is for Windows Vista users but should also work on XP, now to lets begin.

Tools you need.

  • Download and install something that would allow you to monitor your CPU Cores individually if you have quad or dual core, personally I just installed a gadget for side bar on Vista, then monitor it form there. You can download and install the free sidebar gadget here

Now to the troubleshooting steps

Step 1 - I would already assume you have a 720p or 1080p HD videos of your own, now we open it in one of our player like VLC or MPlayer Classic.

Step 2 - Now monitor the CPU core usage on your gadget, if you notice it constantly hitting 99% to 100% while playing the HD movie, that is your main problem it is eating up all you resources and the cause of your slow HD playback, at this point it either you have a slow computer that it can’t handle HD playback or the player/codec can’t utilize your CPU efficiently, if the former you need to buy a new computer.

Step 3 - Now that your convince that your computer is REALLY capable of playing 720p or 1080p HD content, we will need to do further troubleshooting, now we try playing it on other player if you use VLC the first time now use MPlayer Classic and see if you get the same result, if you do go into the preference / option tab or the player’s setting and disable H.264 and Rename the file to .avi (I just read this somewhere) and try playing the file again to see if you have the same result if you did go to the next step.

Step 4 - Now that step 3 didn’t fix or Slow HD playback problem, we might need to install non free codec like CoreAVC, However before purchasing CoreAVC I would like to let you know that the only way I was able to play 720p and 1080p HD videos on my laptop perfectly is by using PowerDVD cost $49, it was able to play all my 720p and 1080p HD videos perfectly, and only utilize 50% on each of my core, leaving me enough resource to surf and do something else on my computer, my Apsire 8920 spec.

Hope this helps.

Thank you for your help on this slow playback. Ive installed the CoreAVC codec, and used KMPlayer but it didnt work until some mods on options/preferences- Decoders- Video Decoder int must disable H.264, AVC1 VC-1, then go go - video decoder ext select default syst and close that screen. When do that be sure to restart KMPlayer and be sure changes has been taken by kmplayer. Thats all! enjoy Playback 1080p. My PC specs:

Thank you i just tried to play 1080p movie with mp classic and that worked just for me. with vlc it was eating my both cores 100% but with mp classic just 55%, so i suggest just use mp classic with hd movie files or use it with every movie file like i will do! :)
