    Are you able to play HD video in 1080 without dropped frames? Will it play smoothly? I know apple says that you need a G5 but I would think a dual G4 1.42ghz would be able to play it. YOu can get HD video trailers from

    I played it on my Quicksilver single processor and it worked, it just took forever to load, but it played fine. The 720 loads faster and is the one I would personally watch. :)

    My dual 533 tends to drop a bunch of frames. I wonder why? ;)

    hell, 1080 doesn't even really LIKE to play well on my G5 SP 1.6.

    720 however plays great. unless you have a 23" screen, 1080 is a waste anyway.

    Not sure if you were asking me, but I've got a Radeon 9000 in my dual 533.

    The 1.8 G5 iMac I'm on right now doesn't play these files particularly well either. It's no big deal though; when this comp was purchased I didn't expect it to do HD.

    So my processor is 400 MHz faster, and yet you get higher frames than me. That's weird. 720 is un-watchable for me.

    Well I have a 2ghz Dothan Pentium M notebook and it can't watch 1080. That said neither can my powerbook 1.67ghz G4 with 128mb Vram.

    720p at 30 fps is 27.6 million pixels a second.
    1080p at 30fps is 62.2 million pixels a second

    and with the H.264 codec there all HEAVILY encoded.
    Yes you DO need a G5 for playback without dropped frames.
    A Dual 1.42+ G4 might be able to playback 720p24 without dropped frames. my two 3.2ghz P4's cant playback 720p30 without dropped frames.

    Hmm. Even 720 is unwatchable for you? That's impossible, because that runs like absolutely no problem for me and I have tons of other programs running.

    I have a GeForceMX 64MB Graphics card.

    It was a POS for months and months and caused MANY kernel panics and it would actually panic on boot and i couldn't boot. All because of its POS ROM... they finally "fixed" it in June. The panics don't happen anymore, but there are still strange flickers in WC3 on the loading screen.

    Wow. Yeah I just got one. Had to update the ROM right away due to loud fan. Seems ok now but I don't notice any real system speedup because of it and thats why I got it. Nothing but hype these cards are.

    For $500 I could have gotten more ram or something.

    The BBC Motion Gallery 1080p movie drops a couple of frames on my system:

    Dual 1.8 GHz G5, 2 GB RAM, GeForce 6800 Ultra, 2 x 160 GB S-ATA HD (Software Apple RAID 0).

    Lowest 16 fps, around 60% at 24 fps. "not smooth".

    I also ran the same movie on the newest Dual 2.0 with 1.5 GB RAM. Radeon 9600 (128 MB VRAM), single 160 GB S-ATA HD:

    Lowest 18 fps, around 70% at 24 fps. "not smooth". Better than my config, but not as smooth as one would hope.

    I assume a Dual 2.3 GHz would be minimal for playing 1080p movies "smoothly".

    d'uh, thanks for that, i looked at that window too, guess i missed it.


    so i was getting 12-14fps on the 720 version
    and
    2 or 3 fps on the 1080

    that's pretty poor no?

    My PB with a iomega FW HD gives me around 22 fps in 720!!!!!!
    very good?
    My dual G4 gives me around 18-20 fps in 720 in internal RAID.

    my 2ghz pentium could watch 1920x or 1280x no problem (with a x300 and 2gb ram) my emac chokes on 720p, and my 3500+ with 2gb of ram and x800 kicks ass in either :D

    btw how do y'all measure frame rates? im just going by how it looks to me as far as watchability :confused:
