1. channels were marked as audio (should be video)
2. The same message id were used for all channels which
   is against the sap (rfc 2974)
3. All channels sent at the same time and then delay is not a
   good idea when sending many channels. Spreading out the sending
   and increasing the delay, makes it more likely to stay under 4000 bits/s
   (even though it still is a very rudimentary bandwidth regulation to
   require recompilation when adding channels.....)
