This seems to be an intermittent problem with any flash video's , not just those on
youtube.

No problem for me

No problem for me

The same problem here... 
It happens only in YouTube. At least www.dailymotion.com and videos.google.com videos 
are working fine.
It happens on *every* youtube video for me, it is not an intermittent problem.

- flash 9,0,124,0 installed
- Google Chrome 0.2.149.27 (1583)
- Microsoft Windows XP [versão 5.1.2600]

This happened to me earlier, the message appeared on top of the video even though the 
video still played.

But it only happened once so I thought nothing of it - I've just tried various YT 
videos and they all work fine.

I am the original poster. It keeps happening, I'm posting my details, so maybe we can 
find a pattern:
- flash 9,0,124,0
- Google Chrome 0.2.149.27 (1583)
- Microsoft Windows XP [version 5.1.2600] with SP3 (Spanish)

I am having the same problem... Unable to play Chrome tutorial videos from Google 
too.

I have the same problem. Ditto with original poster, this error shows on ALL videos. 

Chrome 0.2.149.27
XP SP3

I experience the same problem

I checked and I don't have that problem.
I have:
- Google Chrome 0.2.149.27 (1583)
- Windows Vista
(don't know the flash version)

From the posts above, maybe is XP SP3 ??

No problem here

Google Chrome 0.2.149.27
Windows XP 5.1 (build 2600.xpsp_sp2_qfe.070227-2300 : SP 2)

I've experienced this as well. Its an intermittent problem and I've had it happen in 
other browsers. I think this is a youtube session/caching issue or something like 
that. I did notice that it happens only after I hit the first unavailable video and 
continues until I restart  the browser (kill session).

Google Chrome 0.2.149.27 (1583)
Windows Vista 
Flash: WIN 9,0,124,0

same problem here.
youtube works on firefox, but doesn't on chrome.

I experience similiar problem, but it does not show in evry video, just some. It 
happened before, when I was using Google Web Accelerator with Firefox. Some videos 
show text "We're sorry, this video is no longer available" others don't.

I am having the same issue.  I found this post on Google Groups:
http://groups.google.com/group/google-chrome-help-
troubleshooting/browse_thread/thread/6c2100f9a450ca9d/f0e536cc3cfa766c?lnk=raot

It seems to be an issue with apps that can monitor or modify traffic in and out of 
your computer, i.e. firewalls, antivirus, Web Accelerator, etc.  If you look at the 
post by maabaa, he's at least found a possible workaround for Kaspersky users.

A simple test to verify if your antivirus/firewall is causing the problem with Flash 
video playback in Chrome, assuming you don't want to implement the fix in maabaa's 
post or you are not using Kaspersky, would be to temporarily disable any 
antivirus/firewall software that is running and then try to watch a video on YouTube.  
I tried disabling Kaspersky and I could then see all videos on YouTube.  When I 
reenabled Kaspersky, I started getting the "We're sorry, this video is no longer 
available" error again.  I then implemented the fix in maabaa's post and have had no 
issues since.  This only seems to band-aid the problem temporarily.  Since YouTube 
and other Flash videos play properly for me in Firefox, IE, and Safari, I'm going to 
assume there is a problem with the way Chrome handles Flash content from certain 
websites, especially YouTube.

Okay. This is weird. I disabled web-scan in Kaspersky and all YouTube started working
perfectly. Then I enabled again... and it was still working. I'm confused.

The workaround described by maabaa at

http://groups.google.com/group/google-chrome-help-
troubleshooting/browse_thread/thread/6c2100f9a450ca9d/f0e536cc3cfa766c?lnk=raot

worked for me...

It also solved the problem described in  issue 345 .

i have the same problem, when im trying to watch a video "We're sorry, this video is no longer available" 
appears. and that wasnt yesterday i could watch any video but not now.

I have the same problem. The video I was trying to watch worked earlier this morning, 
but now it just shows that the video is no longer available. I tried the same url in 
IE and it worked fine.

same problem... in addition the videos on the front page where they cycle through 
different videos; if I click on one of them, i get errors intermittently. Youtube has 
a lot of problems for me. I have to type in www.youtube.com for it to work. I cant 
just type youtube.com. ALL videos say this video no longer exists.

I heave the same problem with chrome and kaspersky. I change the security level at 
web anti-virus and now it is ok.

Oh yeah, I have the same problem but it was solved by stopping Kaspersky.

I have the same problem, but it has been resolved by Kaspersky Anti-web 
Virus stop.

(No comment was entered for this change.)

In kaspersky I had to disable Web Antivirus, Anti Phishing and Anti Banner. Not 
Chromium works with all sites

I think its the Kaspersky... y had the same issue, i couldn't load any video, the 
"This video is no ..." message appeared. But I disabled the Kaspersky protection and 
then I could load videos. 
But... apparently, after some time, when you restart the Kaspersky protection the 
denial messages appears again.

Deprecate Area-Plugins label in favor of Area-WebKit and a separate Plugins 
label (reducing number of Area- labels).

hi,
got the same issue, BUT it's loading the video...but only 2 or 3 sec. then it 
stops... :S 

no hardware problems, no software conflicts...so...what's this about?
GOOGLE, pls fix those bugs and release an update!! 

thanks

This is probably not a Plugin issue.

Clearing the cache made this work again, which leads us to believe this may be some 
kind of HTTP caching issue.

Hi. Many videos area appearing with that message. I tried many musical videos, from 
Maroon 5 to The Beatles, many were unavailable. The "Makin with the Magilla", news 
clips, documentaries, you name it. I wonder if it has sometiong to do with copyright 
infringement. 

Adding Google Chrome to the trusted applications list in Kaspersky resolves this and 
all other issues related to Flash Video and logins.

I get the same error, and don't use any anti virus.
However, once in a blue moon it works for a night.

then dead the next day, or even hours later.

Me 2 i dont use any av. but i have a web filtering proxy.
it happends sometimes, not all the time but once it happened the problem persists 
until i restart chrome together with my proxy.

I experience the same problem.

i having the same problem...
when im watching any flash video the action script gets in a never ending loop that
eats all of my CPU. It normally either crashes the whole tab or it times out and or 
ask me if i want to unload the flash plugin on that tab. now i know it does this on
both XP home, pro and vista since i have put chrome on all my computers. the vista
one even has a dual core. even though the hang ups are not as bad on my vista
computer, it's still pretty annoying...

No problems here.

Right at the very moment, this video works:  

http://ca.youtube.com/watch?v=KRfMZZfCyPs&feature=related

but most others do not.

I have fixed it, although I don't understand it.
On a lark I searched for my ISP (Shaw cable) and proxy.. and found out they have an 
optional proxy server... entered that in.. and now everything so far works...

Now why would vids work through proxy and not direct?

I have the same problem as the original poster. However, there is an occasional video 
that does work.

Chrome version   : 0.3.154.9
Flash version    : 9 and  10,0,12,36 (both exhibit problem)
Tested IE 6      : OK
Tested Firefox 3 : OK

Attempted workarounds:
Disabled BitDefender Free AntiVirus and killed all BD processes : FAIL
Disable Windows XP firewall : FAIL

I have the same problem...can you guys fix this?

Anotov thank you very very much. Adding chrome to trusted zone resolves the issue.

I had the same experience. However, when I lowered Kaspersky web anti-virus 
protection to minimal or "High Speed", I am now able to see youtube videos. The level 
of protection I had was set to "Recommended". I don't feel comfortable leaving it at 
minimum security level, so I switched back to "Recommended" and use FireFox to view 
the youtube videos.

Chrome: 0.4.154.25
Windows Vista Home Premium SP1
Kaspersky: 7.0.0.0.125

 Issue 4700  has been merged into this issue.

This problem seems to be related to personal firewall software not recognizing 
Chrome/Chromium.  The firewalls compensate for Firefox and IE but fail to compensate 
for Chrome/Chromium.  Over time as firewall vendors update their software this 
problem should go away.

If you are having this problem you should contact Customer Support.  It is sometimes 
helpful to point them to this URL so they can see the conversation.

As there is nothing Chromium can do to change the firewall configuration, I am 
closing this as Won't Fix.

well, I have no firewall installed and still with this same problem occasionally, so 
it doesn't seem to  be only connected with that!

Are you saying that every so often ALL YouTube videos say "no longer available" or 
that some work and every so often one doesn't?
