Yes the Mezzmo app for Samsung does not support chaptering, this is why I asked if you were using the app as this would have explained why it was not working. I would greatly appreciate it if you would help us by installing Wireshark (you can download it from
http://www.wireshark.org) and following a few steps:

What you will need to do in Wireshark is the following:

1) turn off your device
2) stop the Mezzmo server if it's running
3) run Wireshark
4) go to Capture -> Interfaces
5) in the dialog that pops up click the Start button opposite your network card (if you have multiple, please choose the one that's connected to the
device)
6) turn on the device
7) run the other media server and try streaming a file to your device
8) click on Capture -> Stop in Wireshark
9) click on File -> Save in Wireshark and save the file as a Wireshark/tcpdump format (default)
10) zip it up and send it to me

If all goes well, it should be a large file and it should contain what we need to know to get Mezzmo working with your device properly.
