Yeah. Because the IP address is not reachable, this will typically wait for 
the full TCP connection timeout as coded in VLC (the default one would be much 
worst yet). This can easily be reproduced with:

$ wget http://mafreebox.freebox.fr/freeboxtv/playlist.m3u

And you're lucky that your DNS is fast to resolve; that's not the case for 
everyone and can add another 30 seconds of wait... I've (had to) use networks 
with flaky DNS.

AFAICT, waiting for network I/O in start-up or in UI loop is not simply 
acceptable and that is all. Even if it can be fast in most cases, there are 
always too many slow or failure cases.
