which reminds me of an issue I've been unable to diagnose, similar but
not the same:
viewing flash video from any site showing flash videos (youtube, cnn,
etc.) using FF, it'll play along very nicely, but every 5-15 (or so)
seconds, the video will pause for 1-3 seconds while the sound continues,
then the video starts moving again.
I recently noted that the right-click menu in the flash window contains
an item something like "info for nerds", which shows among other things,
dropped frames.
so if I watch that window. whenever that pause occurs, as soon as the
video resumes, that window shows a clump of dropped frames. I can't
correlate the timing with anything else that's running. Not even the
Folding At Home client, which I can stop and the pauses still occur.
This is on a six-core AMD Vishera processor, which should have plenty
of ponies under the hood for flash video, even when FAH is running.
so far, I've not had another browser sopporting flash to test.
But the time is coming when I'll get irritated enuff to go find one.
