vista computers cant connect to my multicast

[sjlsam]

Macs and XP can connect to my UDP 224.0.0.1:1234 multicast just fine

when i try to connect using a vista machine i get
"VLC is unable to open the MRL 'udp://@224.0.0.1:1234'."

problem occurs with both 0.9.6 and 0.9.8a

VLC is an allowed firewall program and udp port 1234 is open on the firewall

any idea how i can get this to work for vista users?

Can you try turning off the firewall?

Some debug outputs could help too. Open "messages" window from VLC GUI, set verbosity to 2 then open the stream. Look at debugs, paste them if they doesn't show you the problem (past using "code" tag).

does the same thing with the firewall off, this is what code im getting in Messages
All the computers are on the same internet and the same subnet, ive got two XP computers and two vista computers, all using 0.9.6
Both XP computers connect, both Vista computers error out with this message (even with run as administrator, compatibility mode set to xp, and firewall turned off)

Please, use "

Code: Select all

" tags to embed your logs. Can you try with a different multicast address like 239.0.0.*? Have your Vista computers more network interfaces than your XPs? [quote]on the same internet and the same subnet[/quote] Confirm you are using the same private network? Multicast is not routed over the internet (roughly) You can also try to install wireshark on one of your Vista, and try to receive the stream with VLC while capturing the network card in promiscuous mode (no, I am not mad:) or hope so).
