Carlos,
I notice that you have changed:
FEC = 8x8/128
to
FEC = 8x2/128
Was this on purpose? This could definitely cause a failure such as you
describe. The number after the x indicates the level of redundancy in
the multicast stream. A higher number means more redundant streams, and
makes it less likely that a client will miss part of a stream.
Try setting it back to 8x8/128 if you can, and let me know how that
goes.
Thanks,
-Brian
