I think if you mean an on-site FM transmitter, you'll be fine, but if you mean you're going to send the audio to a regular
broadcast station several miles (kilometers) away, and then have it broadcast back from there, you'll have a serious
synchronization problem. Even fairly slight non-synchronization of lip movement with pronunciation is quite disconcerting.
The same is true of movies portraying the playing of a musical instrument, especially something like a piano or a drum.

I can't answer about vlc, but the above is what you're dealing with.
