Most of us seem to be finding the new HLS streams are rock solid, even
with quite poor broadband bandwidth. There are suspicions, however, that
some of the unreliability issues that some have been having with the HLS
streams, particularly the Live streams, might be down to slow or
unreliable connection to your DNS server, or even problems with your
chosen DNS server misbehaving. The HLS streaming method is sensitive to
such issues, which you may not notice with other Internet usage. See
this post:

Your chosen DNS server (probably set by your ISP in your router) may
have problems. Or it is possible that your broadband connection or home
network is just 'on the edge' and drops a small percentage of network
packets - not enough to be noticeable in most use, but enough to lose
the odd DNS lookup message, which could cause havoc with the HLS
streaming. This is all conjecture - we don't have any hard evidence of
this happening with anyone using the alpha3 BBCiPlayer plugin (yet). If
this is a regular occurrence for you, it sounds like it is worth trying
to trace the problem.

A simple thing is to just try using a different DNS server. PasTim
suggests Google's at 8.8.8.8. I might be helpful to try a utility
program that tests out your DNS performance and point you at a better
server. A quick google came up with
https://code.google.com/p/namebench/.  Disclaimer: I can't vouch for
this program, I'm running it on my laptop as I type this, but it is
taking a long time...

If that doesn't help, or before even trying that, we should be able to
see something unusual happening in the LMS log with some debug logging
turned on. I suggest selecting 'debug' logging for both
(network.asyncdns) and (plugin.bbciplayer.hls). You do this via the
settings page of the LMS web interface page - it's found under the
'advanced' tab and the 'logging' drop-down menu. This will produce a lot
of log output while playing the BBC streams, so don't leave it on
permanently - just do it for one test while you are having problems!
Attach the whole server.log file here if you can (I don't where that is
located on OSX).
