Windows 7 - full screen youtube video lockup (soft soft)

I freshly reinstalled my windows 7.
before and after the install,
when I watch videos on youtube.com (that's the only example atm),
the videos play great, flawless framerate, no matter the quality.


but they will randomly lockup. pause. only while in fullscreen.
high speed internet, videos have completed downloading, streaming speed isn't the issue.

if i press ESC to the video minimizes to a smaller display and works flawlessly,
if i press full screen again, the video continues flawlessly, untill 5 or 10 seconds later,
no specific time, they may more may not pause again.

no other system annoyances that i can recall.
i tried updating divx, although Ive never had to install those to watch youtube.



any ideas what could cause full screen video lockup?
ESC and a refullscreen instantly solves the issue, but i have to do it a few times throughout some videos.

reinstall java maybe? seems like I had to install java to watch youtube. i forget.

I would make sure my Java script was OK. Do you run Trend A/V by any chance. This can block Java! What's you broadband speed? Does this happen at all times of the day or only at specific times?

I've got the same issue. I haven't tackled it yet so I'm not sure exactly what it is, but I've heard it's a problem with Flash hardware acceleration. I'm not sure if Youtube still uses flash, but if other sites are doing the same thing it might be that.

See if using YouTube - Broadcast Yourself. makes any difference.

Hi Manhunter
The OP said "but they will randomly lockup. pause. only while in fullscreen.

But the Beta version of YouTube HTML5 Video Player doesn't support Full Screen!

Apologies Sir
