YouTube: Sound but no Video

Posted on 2011-03-03

I went to YouTube and played a video.  When that was done, I went to watch another video but the screen was blank (white) where the video was supposed to be.  The rest of the page displayed without any reported errors.  The odd thing is that the sound for the video was still playing.

So I did some looking around and decided to clear the Temporary Internet Files and Cookies...  Voila! It worked!

So I watched another video, and when that was done, went to play a 2nd video and now it is back to the blank white screen with the sound from the video playing like before.

So I cleared the temp files and cookies several times, rebooted, defraged, reinstalled Adobe Flash Player and a few other things... Nothing seems to work better than clearing the temp files and cookies, but even that only gives me the ability to watch 1 video.

One thing is odd though, Adobe Flash keeps asking me if it is ok for the webpage to run it, which I am not used to seeing... I tell it to run on this page only.  Should I tell it to run on all pages (seems the only thing I haven't tried in regards to Adobe Flash).

Any suggestions on what it might be?

Maybe you have to lower your security settings for playing - besides the adobe flash ?

The security settings are on the default settings as far as I can tell.  How risky would it be if I told Adobe Flash to allow flash content on all sites without warning me first?  It seems like most computers do that already, but I have never adjusted it and don't want to over compensate for this problem.

Is it safe to simply click "Allow add-on to run on all websites" so I will no longer get warnings when flash content is being viewed?

Then again, why would it only work once, and then no more?

It's hard to tell at his point but frankly - I would do that.

Telling Adobe Flash to run on all websites seems to have made the videos work reliably.  Let's hope I don't have any significant security issues as a result.  As long as I keep the Flash Player updated, I should be fine for the most part, right?

You know, you never know... :) But like you said - either you do what everyone else does or you will have issues with browser.
Is this FF, IE, Chrome, Safari, Opera ? Did you try using Flash Player on any other browser ?

I only use IE8.  This machine is using a fresh installation of Windows XP, fully updated on MS Update.

I know that this ticket is already closed, but I thought the problem had been resolved, and it started happening again.  I did some more reading and was able to find a work around for the problem.

As it turns out, the problem is not a software problem, but more of a hardware problem.  THere is nothing wrong with the hardware in this case, but there is an issue of timing between the different hardware items (video card, sound card, cpu, etc...) where the sound would play but the video would not.

To resolve the issue without replacing any hardware, log onto a website with an embeded flash video in the page.  Right click on the video, click settings, and disable Hardware Acceleration.  This allows the video and audio to play only as fast as the slowest componant, and everything plays fine.

I hope this helps someone else in the future with this problem.
