I have recently determined that I am unable to play video on Flash. This occurs across many websites. My computer
Power Mac G5 Tower (8 core, lot'o'RAM)
Snow Leopard (OSX 10.6.8)
I have downloaded and intstalled the latest version of Flash. Unintstalled, reinstalled it, tried installing a legacy version. Rebooted, reinstalled my browsers etc,. Across all three of my browsers- Chrome, Safari, Firefox) I can see flash interactive content (and the the "flash is installed" graphic on the adobe Flash page), but once I try to play a video, I get a "spinning blue circle of anticpation" thingie- and no video ever comes up.
I have done as suggested and turned off hardware acceleration, turned on "allow 3rd party..." etc,. and done a scad of other things in the "Global Settings", all to no avail.
Here is an example of a website with a flash video that I cannot play. It is the Second video on this page (the first, a YouTube video plays just fine.)
Since you're running a PowerPC based system, you'll definitely want to have the following version of Flash Player installed.
However, I suspect you're running into problems with content providers blocking playback on this older version. Unfortunately, I don't have any official good news to give you. The version of Flash that supports PowerPC is no longer supported. Unofficially, some members of the public have been able to work around this problem.
I followed the letter of the intructions exactly, twice, to no avail. Still no video. Interactive content, yes, but no video. I even tried installing the latest version of flash afterwards. No luck.
Would someone else with a PowerPC Mac and flash give the linked video above a try?
