    AFAIK Dark_Shikari's i7 works with it, and while i cant find his post right now im pritty sure his i7 laptop has the Nvidia VDPAU ASIC in there, dont know if he uses that though for his testing.

    that i7 laptop is used for refactoring his x264 patches to get better throughput etc OC.

    it seems [Dark_Shikari] the x264 developer took it directly off the BBC : Planet Earth Birds BR disk as far as i know rather than the studio masters as the visual quality isnt that good.

    go ask him about it over on freenode #x264 if your that interested in the reasons, and he will tell you why its so hard to decode, and potential ways to make your decoder and processing chain better etc perhaps, so it is real world material, go buy the BR and try it yourself perhaps.

    He is. My laptop plays every 1080p movie I've thrown at it without batting an eyelid (and I've thrown many).

    Frankly, I couldn't care less if it drops frames on a benchmark, when every real world test works smoothly.

    try it again with an i7,or even i5 and i3, i dont think you will have to many problems then.

    will someone please set the 1 minute time for the board back to how it used to be, as more than a minute passes and it wont let you edit Your posts to add or edit them, 10 minutes is a good generic limit if you really must set one.

    That has been a joke "benchmark" floating around for quite some time..

    If you re-encode it to proper levels, it will play just fine.
    err NO, thats a nice bit of FUD or wrong assumptions there ghost_o .

    to be clear, it is Not a joke "benchmark"
    it infact plays fine on PS3, popcorn,and the right PC hardware and decoder,as it stands right Now,(putting the video and audio into another container being perfectly fine if you need to OC but No Re-encoding the video to cheat) No re-Encoding down to a lower spec, thats the point.

    sure, its hard to decode, but it can be Decoded and played back smooothly Today,coreAVC helps OC.

    if Your H.264 Decoder Cant do it. then its time to sit down and seriously refactor YOUR software decoder until it can,just like BetaBoy and his team did.

    theres a reason that clip is used as a benchmark and its because its hard to play but not impossible on todays PC hardware, dont blame the clip, use it to see if Your hardware and software decoders good enough, and if not make them good enough like others have done, simples.
