Live DVD (14.04) works fine but problems after install

[Bob FromLynn]

Thank you Mark, Andre, and Goth Spark lmvu for your prompt replies and suggestions!

1. Yes, I already installed the "Lubuntu-Restricted-Extras" package which installed the flash add-on for Firefox.
2.  Chrominum would not even run so I couldn't try that suggestion.
3. I downloaded and installed Chrome as suggested but it would not open and returned a "Hardware no longer supported" error message.

4. GOOD NEWS! I tried the suggestion (and link) to set Youtube to view in HTML5 and IT WORKED!!!

Thank you for all your help!
Regards,
Bob
