Flv issues

hello all

here is a mystery i have about 30 hours in trying to solve, including reading every tutorial i can get my hands on.

if i create an flv straight out of final cut, and load it into flash, the audio plays fine, but the video is basically moving at not even a frame per second. (fps is correct in final cut export option)

if i upload the same flv and test it on vital streams site, same result.

if i export the movie out of final cut,and import the .mov into flash, the vid plays fine but no sound(i have tried every method for sound import). i can load the aiff seperately no problem as a workaround.

the quality of the exported flv is far superior, at least as far a the few frames i get to see.

if i load the .mov into flash, then export it as flv out of flash, and reload the flv again either as an external movie(on media playback component) or as embedded, the sound is gone.(actually the sound never made it in to begin with–i dont understand this). however, if i use flas to convert the movie to flv, at least the flv plays at the right speed, minus sound. it seems it is an issue with the flv converter in final cut.

i have tried every combination. i am using the 2004 mx pro trial.

thanks to anyone that can point me in a direction to get help.
