Unhappy Videos on Ubuntu are choppy (Youtube), help?

On my computer with Ubuntu 10.04, I attempted to watch this video Firefox told me that I had missing plugins, so I installed them. It was 3 of them, I forgot there names. They all ended in .swf though. After I installed them, I rebooted my computer. This time, the video showed up but when I played it, it was very choppy. The video was loaded 100%. I then went to youtube and attempted to watch a video and the same thing happened. Basically the video was play, stop, play, stop. It wasn't a continuos motion.

I then used the same internet to play those 2 videos on my crappier specced Windows 98 computer. It played the videos just fine. Got any ideas of how I can get the videos to play fine on the Ubuntu computer? It is a much better computer than the Windows 98 one, so I don't get why I'm having this problem with it.


PS I'm not very good with computers. So, I would appreciate a dumbed down version of instructions or better yet, step by step help.

Install Chromium instead of Firefox. To enable the repository and install Chromium:

Open Synaptic (System -> Admin -> Synaptic Package Manager). From the menu bar, from the Edit menu, select "Repositories". Software Sources will launch. Click the "Other software" tab, and then click the "Add" button in the lower left corner of the window.

In the dialog box that pops up, type in ppa:chromium-daily/ppa in the box and two new repositories will be loaded in there. Click Close, then Reload. After the software listings are updated, search for "chromium-browser" in the search box in the upper right of the Synaptic window. Mark the one package that shows up for installation, and then click "Apply". The package will then install automatically.

Now, to run Chromium, just select "Chromium Web Browser" from the Applications -> Internet menu.

If you're still having choppy video in Chromium, make sure you have true Adobe Flash, **NOT** Swfdec or Gnash (the other two plugins in Firefox's Plugin Finder) installed. Remove Swfdec and Gnash in Synaptic.

Plays fine here on both my Slackware and Ubuntu boxes.

The reference to *.swf files puzzls me. That means "ShockWave Flash." The don't sound like Linux file names.

What are the contents of your /usr/lib/mozilla/plugins directory--that's where Firefox plugins are usually stored in Linux. The Adobe Flash plugin is named

You might try getting the plugin directly from Adobe. Click on the Get Flashplayer item and "select version to download" the *.deb file.

Then open up the file manager ("Places" on the Gnome menu), go to your download location, point the mouse at the file, right-click, and select "Open with Gdebi installer," and follow the instructions to install it.

These are the contents of my Mozilla plugins folder on my Ubuntu computer:

dir /usr/lib/mozilla/plugins             nphelix.xpt                   
Afterthought: There's just a chance it might have been net congestion, depending on the time of day and the alignment of the planets.

I believe gnash and gnome were 2 of the 3 files that I installed. I don't have the PC with me so I can't confirm that.
