Quicktime or Flash?

I don’t have any sound on my edited .mov playing in browser.

I have a video for a client who’s original video editor put in the wrong phone number at end of video then moved out of state. I took the wmv, edited it in Premier Pro 1.5 and compressed it in Premiere with sorenson 3 into a .mov . Then since it was still too large i took it into quicktime player, imported it and compressed it with sorenson3 again to get it down to 8mb.

It plays on my computer but I went to the clients computer to show him and the video played w/o sound on several, giving the error that you don’t have the right plugin and the correct one is not avaliable on the quicktime server.

So the dillema is does anyone have a fix or should i re-render in a larger filesize or should i try and take it into flash?
