youtube stuttering link didn't fix the problem
Thanks for the suggestion Forubu but it didn't fix the problem.
I've since tried other fixes to no avail as follows:
- I tried Dooble & Konqueror browsers but had the same problem, suggesting the problem may be in Ubuntu itself
- I googled the problem and followed the advise on other forums & web-sites, including updating Adobe Flash but theses didn't help either.
- Oddly, some youtube videos play fine and then others don't.
I'm open for more suggestions.
