    I'm considering getting a used G4 MacMini and hooking it up to a 1080p projector mainly for movie watching. Why not Intel? Because I have a few old OS 9 games I like to play from time to time. There's no classic environment on the Intel Macs.

    I know the Mini supports resolutions up to 1920 x 1200. But just because I can, does it mean I should? What is the performance running H.264-encoded full HD 1080p material? Does it run smoothly?

    I saw the Bare Feats review here, but they don't mention video playback.

    Also is there any hardware extension, anything, that would allow a dual-screen setup? That is, not mirrored, but two independent screens.

    I'd be suprised if a G4 would do 720p without dropping frames, much less 1080p. Apple has some system recommendations for H.264 playback. One can probably get by with a little less than the recommended minimum systems though. In my experience, the G4 Mini will handle 2D desktop work at HD resolutions, not video and 3D.

    Depending on your budget/needs, Matrox' DualHead2Go might be what you're looking for. For my needs, I found it to be too expensive as well as too limited.

    I have a 1.42 GHz G4 Mini and I would say that this won't work. It has been a while since I tried H.264 1080p video (maybe the changes in QuickTime 7.2 help out), but when I tried it a LONG time ago it was unwatchable. 720p is okay if I remember right, but 1080p is too much for that system.

    I think I'll rule the Mini out then.
    The Matrox looks interesting though.

    Yeah, 1080P HD playback on a G4 mini is virtually non-existant.

    Hey guys, I really hate to ask a question in this topic, so sorry OP, but I didn't want to make another topic for the same question..

    What about the Intel Macs? I'm interested in a New Mac, the mini seems to be pretty perfect for what I want, but I have a nice 61 inch HDTV, at 1920 x 1080 resolution, is the text readable from say the couch at 10-12 feet away?

    No way a G4 Mini can process HDTV at any decent size. I discovered the same problem with a last-rev powerbook and movie trailers. Simply can't handle it.

    C2D iMac on the other hand, is absolutely fine - even at full-screen resolution.

    My intel Mini reads fine at 10 feet from my couch on a 42" sony wega. But it is hooked up through the vga input. I am not at my home right now, and I cant remember the resolution setting right now, it's been at least a year since I adjusted it. You always have ctrl+scroll to magnify though :)

    1080p minimum requirements

    I think you need either a Dual 2GHz G5, or a 1.66GHz Intel Mac Mini as the minimum requirements for 1080p within Quicktime.
