<@dalias> reynaldo, if ipv6 is enabled, what the network code _should_ do is:
<@dalias> first try the host string as an ipv4 or ipv6 numeric address (order these are tried doesn't matter)
<@dalias> then try hostname lookup for ipv6/v4 in the user's preferred order
<@dalias> however what it does now:
<@dalias> try as numeric ip in perferred address family
<@dalias> try as hostname in preferred address family
<@dalias> try as numeric ip in other address family
<@dalias> try as hostname in other address family
<@dalias> and if the first hostname lookup fails
<@dalias> it mp_msg's an ERROR
<@dalias> which makes the gui popup a window
<@dalias> so if ipv6 is your preferred address family
<@dalias> and you use an ipv4 numeric host
<@dalias> e.g. http://1.2.3.4
<@dalias> the gui will always print an error that it failed to lookup the name as ipv6 hostname
<@dalias> and it does so in the evil popup box
<@reynaldo> humm, that mp_msg wrapper is disabled on cvs
<@reynaldo> as far as i can tell
<@dalias> the error dialog one?
<@reynaldo> yep, just saw it a few hours ago
<@dalias> in any case it shouldn't print an error message even on console
<@reynaldo> yep, youre right ;)
<@dalias> if the text is parsable as an ipv4 or ipv6 numeric address it should never try any host lookups at all
<@dalias> and in fact those lookups are massively slowing it down if your dns is slow

It's good that we have a work-around and understanding of the core issue. Is anybody working on checking in the 
fix, as described in #mplayerdev discussion above?

Thanks.
