Hi,

I have one of these... http://phillw.net/hardware/aDU4RVzY A Win7 machine
with a decent graphic card and 4 GB of RAM. When ever I play flash movies
in a browser, the CPU usage goes from a quiet

Playing Video via a browser is 'expensive'... now let me try it with the
downloaded version of same video.. :

Now, this time the machine is playing the flash video in VLC (That is a new
programme started). So, browsers do not like playing flash movies.... which
oddly enough is not that suprising as they are browsers and not media
players like VLC is). The sooner we are rid of flash, the better.

Ali, if you want, I'll do a compare of html5 vs flash on you-tube to also
show you the difference in CPU time.

Regards,

Phill.
