Hi, Marcel. Please, could you provide the following specs from your computers: a) Media player used. b) Codecs installed. c) Codec used in the files tried to play (also, whats the .extention on those files) d) Chipset of the video graphics adapter. e) CPU. f) RAM. I know this is a pretty long list but there is ussually a mix of facts involved when trying to play those 1080p files and the more info we have the better for tuning up the system. I have been in the past succesfull to play 1080p files (compressed with either X.264 or H.264 codecs and in .mkv containers) with a relatively aged system using an Nvidia 6150 chipset, Athlon X2 5000+ -dual core- and 2GB of RAM. The software setup I used was: 0) DISCLAIMER: If you want to give this approach a try, I highly recommend that you first uninstall all audio/video codecs from the computer to avoid any possible conflicts. I recommend Revo Uninstaller for this task. Please, be very carefull if you are doing this on a production/main/important computer, you could make it unstable or unusuable and loose important data. I am not responsable for any of this as I warned you ;) a) Media player used: Media player classic . b) Codec installed: i.- Here is the tricky part; I bought CoreCodec's CoreAVC software H.264 video decoder. It is a highly regarded codec, with multi-threading support and now, if you have an Nvidia card with CUDA capabillity (available from the 8400 chipset, I believe) it will offload A LOT of the processing from the CPU and use the GPU instead. It is not too expensive, 15$ I think. There is a trial version you can try at: . By the way, I am not related at all with CoreCodec, just a happy customer. If you don't want to buy CoreAVC or it doesn't fit your needs, then you can use K-Lite Codec Pack . It uses the ffmpeg-mt codec which is very good, multithreaded and free, as in LGPL or GPL free. ii.- If you are not using a codec pack (like K-Lite) you will also need a media splitter. I use and recommend Haali's Media Splitter . iii.- If you are not using a codec pack (like K-Lite) you will also need a sound codec. I use and recommend AC3 Filter c) Codec used in the files tried to play: mostly either X.264 or H.264 codecs and in .mkv containers d) Chipset of the video graphics adapter. As I said, this has worked for me using and integrated 6150 Nvidia chipset with 256 MB shared memory. These days I am using mostly ATI HD3200 and ATI HD3300 chipsets in my computers and still works great, althought I am missing GPU processing as I am not using newer Nvidia CUDA capabillities. e) CPU. As I said, this worked on a Athlon X2 5000+ (2.6 GHz stock speed, althought I think it was overclocked to 3.0 GHz, not sure...). The more cores you have the better, of course, but two cores is enough, I think. f) RAM. 2 GB. Please let us know how everything goes for you.
