Create a video file from video+audio and upload it

I have a 1.5 hour WebEx session that had video and audio separately recorded. They need to be put together into one video and uploaded to my web server. I'm open as to video formats - FLV is probably easiest to stream from my web server, but I'm happy to entertain others if you suggest it's better (I need to be able to stream it from a linux web server). ## Deliverables Video details: wmv length 1:22:33 1024x768 29fps Audio details mp3 length 1:30:42 Offset: video starts at roughly 8:09 of the audio Finished video to be uploaded to my ftp site. Audio/Video files will be provided to the winning coder.
