flash is horrible on my machine. if i use that, it won't even play 360p video smoothly. html5 video in tenfourfox is the same: terrible. and by the way, what does CTP stand for?

CTP - ClickToPlugin. I understand your problem but I don't know why it's happening. A G4 machine can play 360P in Flash and HTML5 OK. There must be some issue between Quicktime and Perian. If you can play 720P with VLC that should shine some light on it.
 
i will try tomorrow. my g5 is downstairs and if i go to it i'll wake everyone up because the dogs will start making noise etc etc etc. so i will try to download a video with that ppc media centre program and play it back in vlc tomorrow
 
ok. 720p with vlc WORKS. so it's a start. i used the ppc media center app to download the video, it made an mp4 file and that plays fine in vlc.

If you monitor CPU usage whilst it's playing and it's not going through the roof, I think that firmly places the issues with Quicktime/Perian not the OS.
I've had slight performance issues in the past between various configs of Tiger/Leopard/Quicktime/Perian but nothing as drastic as yours. For what it's worth Quicktime 7.5.5 appears to have a performance edge over 7.6.4
 
no, i mean both cpu's are used about 80-90%
I'm currently on my 1.67 G4 Powerbook, it plays a downloaded 720P Youtube video in VLC at 80% so there's clearly something not right with your G5.
Make sure in System Preferences/Energy Saver/Options processor setting is Highest or Automatic - even so, the lowest setting should be powerful enough.
Maybe you can download a diagnostic disk to check the hardware:

Also, have you benchmarked the machine with Geekbench? You should be scoring around 1600/1700.

Does the machine feel normal in other respects regarding performance? That might be hard to judge if you're comparing with Intel Macs.
 
the geekbench score was 1838, so that should be ok. i just tested it again, because before i was downloading something in the background, and now it uses 50% cpu when playing the video, but that is still a lot compared to the 80% from your powerbook. and the machine feels ok in normal use.

Well benchmarking and percentages is never an exact science on these machines, I often get wildly different marks for no apparent reason but I'd say your 50% is acceptable. Poor Flash, HTML5 and Quicktime time performance might come down to a bad software install - I've had this before where the only solution was a complete re-install.
You could still follow the procedure I indicated before for TTF/Coreplayer but instead point the plugin to VLC instead?
 
if i do that, it downloads it first. it doesn't stream it.
That's correct - it's an inconvenience on long videos but does lower the CPU load. If you search for TFF plugins, there might be something more suitable - I've only looked at a few.
At the end of the day, we are talking about computers resigned from duty ten years ago trying to tackle web protocols that are changing constantly - however, based on the machines I have, 1.33Ghz and upwards, playing Youtube isn't a problem.
