when "trying" to stream web videos (both Flash and Quicktime), the playback is choppy and the audio doesn't sync very well. I have a fairly fast internet connection 12mb/sec.; cable NOT DSL. Is this issue because my machine is old or my video card isn't good enough? as you can see below my machine is an 867 MHz PowerPC G4... (see the details below).

I have tried to let the video buffer significantly, and still the video is choppy, almost like watching a slide show, rather than a video.

My fear is that my machine is not up to snuff and i will have to buy a new INTEL machine...
any help at all would be GREAT!!!

867 MHz PowerPC G4, Mac OS X (10.4.11), 2MB L3 cache, 1.5 GB SDRAM, Radeon 7500 w/32MB video card, ATA 32 GB HD HFS+

    Hi, unfortunately the Internet, especially Video is bloated & very sloppy, depending on having the latest/greatest for no REAL value.

    Hi-

    For streaming video, you have many factors against you, and the Radeon 7500 doesn't help the situation any.

    I know that a 933MHz QS with a 9800 Pro does a pretty good job with a lot of content, but others are even beyond my 2GHz machine with an X800 or 7800GS.

    Sometimes, a different player can help.
    Ever try VLC?

    Like BDAqua said, a lot of internet content is bloated and sloppy.

    With the content that isn't a mess, code wise, a better graphics card can help.

    Do you have an example or two of specific sites/video of interest?

    Nvidia geforce - can;'t remember the 256MB video card thats the most powerful to get. But, if the OP were to get that card, then I think all his problems would be over.

    That's the 7800GS that I have/mentioned. Even that card in a 2 GHz machine has some sites/ video that are a problem.

    It would be nice if all the problems would go away, but many problems are beyond simple hardware changes.

    Yeah, it just seems that internet developers are simply making everything work for the intel platform, and leaving powerpc by the sideline. I don't agree with this, as not everyone needs an intel based mac.

    here are the specifics as found in System profiler: As you can see the VRAM is very lean compared to your example...

    Chipset Model: ATY,RV200

    Bus: AGP
    Slot: SLOT-1
    VRAM (Total): 32 MB
    Vendor: ATI (0x1002)

    the most common site would be HULU.COM, and just about any video is choppy, unless of course it's only a few minutes long (like a clip) full episode (about 22 mins) are all choppy. Youtube has the same issues as well. I have been somewhat successful by letting the whole video load before playing, but not always, and again, only if the length of the video is short.

    I will test the VLC player you recommended.

    That's also known as a Radeon 7500...

    http://support.apple.com/kb/TA26745?viewlocale=en_US

    A very old/slow card, slower than a GeForce 4MX even,, which cannot cope with today's Videos.

    To lose jitter, downgrade to Flash 8. I discovered this advice elsewhere online. This version will still play on YouTube, but won't work on embedded YouTube in Facebook or Facebook video.

    I traded out my Radeon 9000PRO/128 for a Geforc 6200/256, today, and things went even better. I upgraded again to Flash 10 and jittery video has returned but not as bad, and not bad at all on lower grade like 360p.

    My reported experience is with an upgraded Sawtooth, so I don't know how well things will translate to other models. I suspect, if I was running 10.4.11, things would work out even better.

    Say I'm trying to figure out why I'm having Jittery problems too, I just upgraded my speed and was hoping that was the problem, I too was looking at Hulu for better watching of video, no luck, my jitter has calmed downed but hasn't gone away, here are my specs- 1.7 GHz processor, video card is ATI 9000 Mac Pro/ 128 MB, my Flat screen is aw-some a VeiwSonic VP 950b, I've maxed out my Ram 2 GB, say any thoughts on mine, oooops forgot my internet speed is- 10.31 Mbps or 10306 Kbps or 1288 KB/sec, thanks for any input.
