Hi

Thank you Doug for your answer

I totally disagree.
Concidering a FM signal travels with about the speed of light, there will be 
absolutely NO sync problems due to the distance af the broadcasting.
(300.000 km / second. So 30 km will introduce 0.1 millisecond of delay. One 
frame film is 42 Msecs.)

If you have a tremendous amount of equipment in the pipeline between input 
and arial / antenna, that might introduce a delay.
Now that will be constant, and VLC can compensate for that (it's an easy 
menu item)

If you have an internet connection, have a look at VLC's sync play, start 
with command line --control netsync --netsync-master etc...
Or, get Syncplay (google syncplay vlc).
Have two copies of the movie (one could be sound only), the network will 
keep 'm sync worry free.

hth,
Bouke

Yes, you're right, that is the configuration. My idea is to have the regular 
FM
transmitter as master, and the video streaming driven as a slave using an FM
receiver to synchronize the video with regards to the audio...
