First the bad news:
You need to be running Leopard to do the following:
Now the good news:
I am in the same boat. I cannot watch flash videos on the BBC website or on BBC iPlayer, although all other flash videos (YouTube for example) are fine.
For reasons that passeth all understanding, they work with the PPC version of Firefox, called TenFourFoxG5.app, once you have anabled plug-ins, as it does not natively support Flash.
You can download TenFourFoxG5 from here:
Now for the interesting bit: TenFourFox, like Firefox, does not support most plug-ins. Unless you are prone to headaches (in which case don't) you can read about that here:
But there is a workaround!
Open TenFourFox and type in the address bar: about:config (no spaces) and click return. This gives you a warning that it might harm the application. Ignore that and click on 'I'll be careful, I promise' and you get the config file that you can edit - with great care.
Look/search (scroll down) for: tenfourfox.plugins.enabled
Set it to true. (Double click it to toggle it)
Now close TenFourFox, open it again, and Flash will now work, as it now uses the plug-ins that Safari has stored.
I am using Flash 10.1.102.64 in TenFourFox and it works just fine.
I thought I had it fixed, thanks to you: tried the TenFourFox configuration, no problems.
But I'm still getting the same problem; 'wrong' version of Flash player, and then inability to upgrade.
Oh well, just have to remember to set the recorder. And catch up with radio instead ...
Thanks for the info anyway.
