    I own a 5920G with HD-DVD and 1.5 Ghz Core 2 Duo, and a website(Nero) said that you need minimum 2.0 Ghz Core 2 Duo to run HD-DVD. Is this true? Will it lag while playing the movie outputted to 1080p? I know that HD-DVD players don't have CPUs in them, but does it impact it with a laptop?

    It very well can. The CPU is responsible for decoding the video.

    If you have a powerful enough graphics card (mid level at least) then you might be fine with a 1.5GHz.

    it probably will be ok but dont expect to do much on top of hddvd playback.

    I remember that the Toshiba HDDVD gen 1 players had a P4 2.0 ghz on it so keep that in mind

    That sort of worries me then. The 5920G has an 8600M GT 256 MB(up to 1 GB if shared). If I put it on charger, I can put the CPU on max, but still, I'm going to struggle a bit.

    AS 5920G with 1.5ghz cpu plays back HD-DVD movies fine. I have verified it. Keep in mind it has a core 2 duo cpu and a 8600 GT video card.

    The video card is definitely the key to help.

    FYI, but the P4 suck. The P4s are also now dirt cheap which is why you would find one in a HD box.

    There should be no problem. What Nero means is probably you would need C2D 2.0 for software decoding of HD content but with hardware acceleration of H.264, VC-1, WMV, MPEG-2 done by 8600M GT the CPU is not that important.

    yep the 8xxx series nvidia cards reduce the cpu load to about 20-30%

    with the old 7xxx series the cpu had to do all the work

    80-100% cpu load with the old cards!
