Full screen problems on Youtube with HD4850

I've just put in a new graphics card HD4850 (with latest drivers) and whenever I try to play Youtube videos in full screen with hardware acceleration enabled the video doesn't display (only residual artifacts remain - like when I move my mouse across the time bar the times will remain on the screen, it's almost as if the screen doesn't refresh at all) but the sound works.
Of course, I can watch videos with hardware acceleration disabled, but the quality sucks. The most annoying thing is that my previous card (ancient Radeon X550) that I've just removed was able to play hardware accelerated full screen videos without a problem.
If anyone can identify the cause, I'd appreciate it.
Cheers

My specs:
Windows XP Pro SP3 32-bit
Mozilla Firefox v10.0
ATI CCC v12.1
Flash v11.1
 
if its only happening in youtube then it seems to be the drivers.

the new 12.1 drivers are pretty sucky tbh, go back to 11.12 and you shouldn't have any problems xD
 
Haha :D
Btw, I did try 11.12 and it didn't work.
I've just tried 12.1 again (but with cursor and bitmap accelerations disabled) and for a moment it worked but then I exited full screen and tried it again and it broke.
It must be the drivers then...which means no one can help but AMD.
Thanks anyway. ;)
 
I'm stumped too....I've just tried another video and it's working!
Omg I know what it is....newer videos are immune to this because those are using newer version of Flash, while older use older versions and as such do not work properly.
Meh...should've tried that before posting this xD

You don't understand lol xD
I AM using new Flash, but the videos on Youtube don't.
It's a bizarre thing on Youtube, every video seems to be tied to one specific version of Flash at the time of upload.
Have you ever come across a video on YT that has a different layout and works differently as well? For example the anti-autoplay script doesn't work, or different sub-menu? Well, that's it.
 
erm... i upload all my gaming videos to youtube every few days and watch a lot of videos on there too and never had a problem...

only other thing I can think of is one of the worst possible solutions..

reinstall windows?

what brower you using???

could try a different one... no problems with google chrome here, or reinstall you current browser...

if your using IE9 I will slap you lol :P
 
Hehe nope, I'm not using IE, though I do have IE 8 installed for Windows update purposes. I've tried IE too, but the problem is essentially the same, which eliminates the browser.

I've eliminated the level of acceleration as well, because the problem persists at various levels of acceleration.

I've eliminated drivers too because otherwise the full screen wouldn't work on any video across the board, and since they do (and all other full screen applications work fine too) that leads me to believe the problem is not driver related.

The only thing that remains are older versions of Flash being used by older videos, and I've tried several newer videos to verify and indeed the problem is Youtube and it's crappy integration of Flash.

And not only that, but now I'm finding out that out of older videos only some are affected while others are not.
If you have the same drivers, then try these 2 videos:
http://www.youtube.com/watch?v=9AGemuX7E60 (May 30, 2010) (doesn't work)
and
http://www.youtube.com/watch?v=q1EANf1ydjc (Feb 9, 2010) (works)

All good on my system..

Either reinstall windows or the card is screwed (which is doubtful)

Haha no way in hell I'm going to reinstall Windows over such a trifle :p

Well, it was a shot in the dark to see if you can reproduce it, but you have a different card and most definitely dozens of different applications any of which can be causing this (or it could just be the drivers though I doubt it).

Still my best guess is Youtube and their shoddy Flash implementation (at any given time tons of people on the help forum are complaining about various playback issues so it's not an isolated case).

Other than that, my system is perfectly fine, I maintain it regularly and, although I did think about reinstalling Win recently (haven't done so in over 3 years) I decided not to because there really are no reasons to do that, everything works great (I made sure of that). :)

Anyways, thanks for your input nonetheless.
Cheers ;)
 
I have never heard of this before. Sometimes my youtube goes green in fullscreen, so very well may be a flash error including youtube.

Have you got onboard graphics you can test?
 
Dude, stop asking me questions I gotta go! LOL :D
Nah, I've got some poor man's mobo and bare minimum is all it can give me without GPU.
Besides, I'm bored as it is so some videos will have to do without acceleration. :p
Over & out.
Don't!..ask me anymore questions... haha :D
 
One thing you could try if you don't mind me adding it :P

In youtube, when viewing videos change the resolution to 480p if you are viewing in 720/1080p.

Could be the problem.

Anyways, as your new:
