Actually I can't usually view MP3's at all, & that MP4 was both visually 
& auditorally (sp?) smooth as silk. I did recently (~ 2 weeks ago) do a 
full yum upgrade (FC9 64-bit), which included some browser (FireFox 
3.0.n, also 64-bit) upgrades, maybe that helped. I was mostly extolling 
my ability to view that/any MP4 at all, it was a first :-) ....
