Youtube videos showing 'about:blank' in safari 3 or 4

I used YouView for a while, stand alone app for viewing videos from youtube outside of your web browser, and, for a while, it was better than watching them in safari...

However, I have recently installed CoolIris and found this a much better way to view videos on YouTube but sometimes CoolIris just decides it doesn't want to play a video so I think 'Ok, I'll just view it normally', except when i do, the browser just navigates to a blank page with 'about:blank' in the URL bar (much like it did when YouView was installed) but nothing happens, the video just won't play...

I've tried resetting and reinstalling safari 4 (as I was running) as a consequence of this I'm now having to run safari 3 (this is a problem that will be in another thread shortly) and it still doesn't work...

Any ideas... anyone... I'm getting kinda desperate now!!

Thanks in advance...

P.S. I also checked folders for some sort of YouView plugin left behind, and couldn't find anything.

Its not that the video just won't play... the whole page just never loads, it loads a blank page instead, and it has worked in the past.

Have tried firefox, works fine... I know its something to do with the 'YouView' program I had installed and whatever plugin it used but i have since uninstalled that and all plugins i could find that were related... still nothing!

yup, ran onyx... no luck... but hey, sometimes there is such a thing as being too smart.. just looked into the safari preferences, turns out there's a 'disable youview' button...

who'd've thought it

Have since discovered a 'YouView' folder in /Library/InputManagers when deleted removes the YouView option in safari... so I'm guessing that would've worked also...

Now just the problem in my other thread, safari 4 not installing... check it out if you wouldn't mind... maybe enlighten me a little!
