[Bug 384128] Re: anything played on full screen (except dvd) is very poor and jerky. Sound quality on everything is very distorted unless played on very low volume

[Dougga]

I have consistently seen the same problem: anything played in Firefox
full-screen ON THE INTERNET streaming is jerky.  If full screen is
turned off and one watches in the small screen, it's fine.  By jerky I
mean that the video stops for aprox 1 sec periodically then leaps ahead
to catch up with the audio.

Curious note:  Things work fine on a 64-bit Ubuntu (Quad Core) w/ the
beta 64bit Flash player.
