[mythtv-users] Multicast works, Unicast doesnt

[Rajil Saraswat]

Hello,

I have an iptv stream which can work in either multicast and unicast.
When using multicast ip address (239.255.42.42:5004) both mythtv and
mplayer can play the stream. However, when using unicast mplayer works
but mythtv doesnt. Any idea why unicast doesnt work?

Mythtv log shows this,
