The following is an explanation why I think DNS should not be the main
source of your issue even with your satellite links.

First a general comment about SB player - When and SB player (e.g.
Touch) plays any stream (http/MP3, http/AAC, HLS or DASH) using a local
LMS - the DNS lookup will be done by LMS - the Touch will be told to
play a stream from a numeric IP address.

The BBCiplayer does all the data comms with BBC - the SB player willbe
told to play a stream (i.e. again a numeric IP address) and the source
will be the LMS server.

When BBCiPlayer is playing HLS streams - a DNS lookup will happen for
each 6 sec chunk. Whereas with DASH in 1.5.x using HTTP 1.2 (persistent
TCP) - only one DNS lookup should happen for each live stream.  With
yoru DNS setup I would expect more problem with HLS rather than DASH in
1.5.* unless replies to DASH request tale a long time.  This is why
message in log file are important.
