Tvheadend

Hi,
I set mumuDVB to multicast its steams to my LAN and use SAP announcement.
On my using VLC on my Windows PC I'm able to watch all streams and get also the EPG for each of them.
Info of the relevant steams is:
Ch1: udp://@239.100.0.0:1234
Ch2: udp://@239.100.0.1:1234
Ch10: udp://@239.100.0.2:1234
On my HTPC running TVHeadend I configured three IPTV streams as follows:
Enabled, Ch1, eth0, 239.100.0.0, 1234
Enabled, Ch2, eth0, 239.100.0.1, 1234
Enabled, Ch10, eth0, 239.100.0.2, 1234

I'm trying to open these streams using XBMC and the web-UI, but the only stream I manage to play is the first one and EPG is missing for the one I can play.
The two other streams just fail and looking at the log gives little info

Am I missing something here?
Thanks
