Hello everyone,

I’ve successfully configured wowza and tested it too. The problem is, I have a mpts multicast containing 8 channels. I created stream files and mentioned the program IDs of channels and it successfully decodes all channels to separate streams. **The problem, however, is all the channels are on single udp multicast so when i connect to the first stream fle, i get ~12Mbps bytes in, but when i connect to the second stream file, which is on the same multicast, different program id, the incoming bitrate goes up to ~25 Mbps.** It’s as if wowza makes a second connection to the same multicast. Same thing happens when i connect to the third, fourth stream files, the bitrate increases 3-4 fold. I also tried turning on Datagram port sharing, by editing [install-dir]/conf/Server.xml and setting **/ to true** and restarting the server to no avail. The bitrate is still increasing.

I hope i was able to explain the issue clearly.

Please help
