Select FLV's audio is playing but not...

-- Using Flash 8 Video Encoder (with ON2's codec) to generate
the flvs. They play fine in Firefox. But the video does nopt
display (though the audio does play) in IE 6 and 7 on windows xp
sp2.



-- someone else who used Sorensen's video encoder (which i
assume uses the previous Sorensen Spark codec) - these flvs display
fine on IE 6 and 7.



I seem to be running the latest Flash plugins on both
machines i testing on - though I am not sure the best way to test
this. It does seem like a video codec issue...
