Some Youtube videos are stuttering...

just boot with you backup osx drive that has an older osx to test your theory.

Should read older flash 11.2.1 not older osx sorry

If you are on Safari you you could try using clicktoflash.
Besides blocking flash it will use the HTML5 video container if available. That should stop the stuttering if it is really a flash related issue.

If you don't use safari there should be an option somewhere in your youtube account settings to use the HTML5 video instead of flash.

I made correction older flash not older osx


Still means I don't have a backup osx drive made the problem more difficult. That is okay. You got pissed Since My answer looked wrong.

If you do updates without having a working backup you will get efffed. No one wants to hear that .

Just would have made it faster to find out if the patch broke the the flash.

Your testing on a 2010 macbook pro does help since you have upgraded it to the same version of flash. It proves the patch works on some gear.



Unfortunately without proper backup you have to wait until someone on site with the exact same piece of gear and software lets you know they have the same problem. What happens if no one says yes?


Backups and flash aside:

BTW if your 2011 mini has an oem hdd or an ssd inside matters. Some ssd's have had stuttering issues. your ssd may be failing

Also connection is it wi fi cat 5 cable?

If wi fi can you do a test with cat 5 ethernet .

Have you tried the bad video at 480p vs 720p vs 1080p?

When you tested with both computers were you using the same connection.

Are you in an area that the net slows down at certain times? In my area 2pm to 3pm on a school day the nets gets very slow. The kids come home from school and the net bogs down. So when the mini stutters and the macbook pro does not it the test at the same time give or take 5 minutes.

One last thing consider that everytime you do a patch or software upgrade you entire computer can be crashed. backups save a lot of anger and lashing out at people. peace and good luck with your computer issues.

I get this problem occasionally on my 2.5 amd mini as well.

So much for searching..

i have the same problem,that was the main reason i was installing lion again because on mountain lion it was impossible to watch youtube videos,and on lion it was ok until i updated safari and flashplayer.For me it is really impossible to watch youtube videos,and only youtube because other flash videos are working still fine,i already did a reinstall from time machine without improvement.

By the way Youtube really starts to suck with all the ads ;-)

I had an identical issue with my MBA.

Some videos played back awful. When it started to load, safari would freeze and i couldn't scroll up or down for a few seconds and the video playback was horrific!

Turns out that Google is beta testing some videos to playback in HTML5, which is not supported in safari yet.

The trick is to right click a video that exhibits the issue and see if is says flash or HTML5.

i found that one of the right click options is to remove yourself from the HTML5 beta trial.

After doing that, i have never had an issue on youtube.

I would also recommend enabling hardware decoding in Flash too.

(right click a flash video and check the box, it'll apply to all videos from now on)

i got them on both html and flash,but just on the youtube site,if i play a youtube video from 3party site there is no problem

I don't quite understand what you are saying, but you HAVE TO opt out of HTML5 beta testing program in YouTube.

HTML5 video is suck for Macs.

OP - can you give a sample link? i have 2011 model i5 with 6630 but everything is playing perfectly

I had a problem viewing 1 video on youtube & it was stuttering. So I did this & it worked great.

Go to this website:
http://hoyois.github.com/safariextensions/clicktoplugin/

Now click on the link named:
Download ClickToPlugin 2.6.3

Go to wherever you downloaded this App & install.

Now hopefully your videos won't studder......

I have the sames issues. I think it's Adobe's problem. Or a driver problem but we didn't receive a driver update for the Mac Mini since 2011 ?

i received an updates yesterday and here is the latest
Plug-in version 11.2.202.233

Got the same issue. Fully updated with iMac i5 and Ok-Go treadmill video is very stuttery (http://www.youtube.com/watch?v=dTAAsCNK7RA).

Has anyone got any solutions?

i think the problem is the video itself when you change to 480p.

my config: 16gb RAM / 120gb SSD + 500HD amd 6630 i5

Literally stolen from a previous post of mine, but you can try this to see if it works:

Make sure Flash is up to date. In System Preferences, in the bottom section, click on Flash Player, then Advanced tab, then click Delete All, and make sure ONLY "Delete All Site Data and Settings" is selected. Flash seems to get crapped up over time, this always fixes the problem for me.

This could, not necessarily will, fix the issue.

Tried leaving html5, tried updates, clearing the flash cache (rhyming, ugh), and on 480, that video still stutters. Another issue I have is some videos have a lot of double buffering properly, but others are fine. This was never a problem on my core 2 duo mini and iMac, but it is on my i5 mini and on my iPad 2.

Very frustrating.

Personally, I noticed this too on my 2011 Mini. It got so bad/annoying that I had to switch to Google Chrome. I don't notice the issue on Chrome.. Maybe the Mountain Lion version of Safari will fix the issue for me..

2011 i7 here never had a problem...

I find it curious with all these issues that no one brought up Mactubes? I have used it for years, in fact, I can't remember the last time I was on the youtube site...

http://www.macupdate.com/app/mac/28608/mactubes

I know it involves installing another piece of software, but to be honest? It's a slick, simple interface. It's easier to navigate with, create playlists, and even download content you want to view offline.

Just my observation on it. I will fire up Safari tonight and see if I can replicate what you are all experiencing.

I am having the exact same issue, with the same Mac Mini, however it is not limited to youtube, recent videos playing from my iPhoto library are doing the same thing. Would you mind checking to see if this is happening to you as well?

hi i have a 2011 mini that has the same issue. i have tried the various browsers as well as mac tubes as suggested above with no luck. all videos play fine below 480. it only seems to affect vevo videos as 1080p trailers such as big buck bunny or the avengers trailer they play fine. oddly if i play direct on the vevo website the videos play fine with no issues. could anyone with a 2011 AMD mac mini try the youtube video link above and try changing to 480 to see if they have the same issue? im not sure if it is a youtube/apple or vevo issue though?

edit: just to add i had this issue with lion and upgraded to mountain lion which hasnt changed anything. i have also tried an a clean reload of lion which didnt make any differance.
