Can someone shed light on this matter, What seems to be the problem if upon watching 720p movie rips i get rare delays in display on a particular scene in a movie? Why is this so?


Tried playing it on an hp system and it works well with no

Can someone tell me as to why the hp computer outperforms mine in the hi-def area? and my computer outperforms it in playing 3d games such as L4d, Devil may Cry 4 and other vid card dependent games.

And also What can i change in my setup that will enable me to enjoy hi def viewing at 1080p. :)

I still do not want to buy a new setup... (still waiting for better versions of corei7 and the i5s. If not I'd go AMD but that'll be sometime in the near future.
Just want to make this old setup of miine capable of playing 1080p vids

Any useful suggestions anyone? :sweat:

    You didn't mention a HDD for the system you are having problems with - what has it got?

    Also, try monitoring CPU usage on both computers when playing HD videos.

    It is possible that the 4 year old system does not have enough cpu grunt/hdd speed to play these HD videos. The reason for the difference between the systems (in terms of gaming and watching videos) is that watching videos does not primarily use the GPU - the decoding/processing of the video is done at the CPU. Therefore, a machine with a grunty CPU will play HD media well.

    Take this for example (I did this just now):
    Playing an HD copy of i-Robot on my main rig with a 3.2GHz Core2 Duo uses around 16% CPU.
    Playing this video on a 1.4GHz Pentium M uses around 86% CPU.
    Playing the same video on a 2.1GHz Celeron system uses 100% CPU almost constantly and judders frequently because it cannot process all of the data contained in the video.

    Does this clarify your problem? (To me it clarifies that Celerons are rubbish :D )
    Hope this was helpful.
  2. Hi,

    try to install coreavc to decode the hd video, it does miracle (play 720p ok on my atom 330 with intel crappy onboard).

    Or, read this article about decode hd videos with gpu and Media player classic home cinema :
