Choppy HD Video on G4 PPC MDD

My PPC G4 has a dual 1.42 GHz, 2GB DDR SDRAM, and 2 MB L3 cache.

That being said, whenever i load HD videos and play them back (vimeo, youtube, etc.) they are choppy and play a frame a second, roughly.

i have plenty of RAM - i edit video with FCP and never have problems with that - its only online video.

any ideas as to why this happens?

Power Mac G4 MDD, Mac OS X (10.5.1), Power PC Dual 1.42 Ghz G4

PLEASE NOTE: QuickTime No longer supports flash video in SWF or FLV formats since MAC OS 9.2 and QuickTime 6, if you dont understand what this means listen up, Since Flash video is already a stretched Variable bit rate of audio n video which is not forgivable since your not getting a true constant video bit-rate frame-rate or kbits/sec of streaming media, it will always look crappy, unless the video was originally in a good quality format,

Look for a FREE QuickTime Plug-in called "Perian" it allows you to play most videos on QuickTime without a problem

Look for a FREE Web Browser Plug-in called "Silverlight" from Microsoft, since allot of web sites are starting to use it allot now.

my advice to anyone looking at YouTube or where flash video is heavily used is to

Right click on the video and under Flash settings set the LOCAL STORAGE of this video or websites files to UNLIMITED so that its not in a small cache setting and that usually fixes 90% of most of those streaming problems right there, you could also CLEAR the CACHE or reset the CACHE once in a while in case your browser is'nt set to store too much CACHE

P.S. you could also quit most of your applications or and unnecessary web pages you may have up since that uses allot of CPU usage,

P.P.S. one thing that made a difference on my G4 was to leave no widgets on or active in Dashboard, No unnecessary files or folders on the desktop, except for the hard drive of course, and run "System Optimizer" or "Onyx" once in a while,

Good Luck...

propJust an fyi... Last night I wanted to watch "Top Chef" from my bedroom on my iBook G4, 1 gHz, and only 512 MB ram. This was available through fancast via hulu and Bravo. I started, video stream took off and "loading" was processing. Using Safari, nothing else on. Seemed fine so far...

A few minutes in and it was clear that the full episode jumpy, skippy and out of sync video was doomed.... then a little message popped up, "were sorry, your poor little old Mac G4 is just trying to hard... blah, blah..." ok, well not that exactly that but you get the idea. So I clicked the "Make better video" button and viola it got smaller.

I thought that why don't I just make the iBook screen bigger, in effect making the video lager to fill the screen. I don't really care about 480p, 720p, or 1080p, I just want to WATCH the darn thing. Yup, switched monitor settings from 1024x768 to 640x480 ( egads...) and clicked "full screen" on the fancast flash setting.

Watched the entire episode without skips, and a few little jumps, but overall smooth. Half way in the wife says, "what's that little noise?" ...huh? The fan kicked on and man the iBook was hot but it delivered the whole time. Time for an aluminum liquid cooled fan breakfast table!
