    Hi all,

    Am running Ubuntu 10.10 and am experiencing choppy graphics but only when attempting to watch streaming TV. When I watch a movie .AVI file for example, all is OK even when using different media players. It's when I watch streaming TV within Internet browser's that the above problem occurs. I've tried this in Opera, Firefox, Chromium & Icecat but to no avail. When I watched streaming TV Channels using previous versions of Ubuntu I never had graphic problems?

    Below is the output from lspci -k

    Thanks for your reply TeDiouSish & your heads-up regarding the latest driver version as per your link. After installing the .run file from NVIDIA the driver did indeed update but unfortunately the problem remained. After drilling down to further investigate this annoyance, I can confirm all is solved. After looking at your question of what plug-in I was using it prompted me to check my preferences out. I use Opera browser & under "plug-in options" button, it listed DivXa Web Player; IcedTea NPR Web Browser Plugin; iTunes Application Detector; QuickTime Plug-in 7.6.6;Shockwave Flash; VLC Multimedia Plug-in; VLC Multimedia Plugin (compatible Totem 2.32.0); Windows Media Player Plug-in 10 (compatible; Totem). But the option that solved this problem for me in Opera was under preferences>content>advanced I check-marked the option "Enable plug-ins only on demand". After clicking OK I re-checked the streaming TV website a few times and all is well! The 2nd fix I found was to install the extremely light weight browser Midori. (Website: http://www.twotoasts.de/index.php?/pages/midori_summary.html) In the Terminal enter the following to install: sudo apt-get install midori. My thinking was that after successfully fixing my problem with the Opera preferences; the problem must be due to the heavy nature of the popular browsers that most of us use and their loaded features that enable us to do many activities etc. Midori for me will be only used as an emergency browser for watching streaming Internet TV as it worked flawlessly! Hope this helps others too.
