 Playback of DVB-S radio channels is broken in several ways:

 - Switching to a radio channel can take considerable time and often
 results in failure.
 - After the switch the screen often shows a part faded OSD info or a green
 background.
 - If the channel contains interactive TV (e.g. BBC radio) then OSD
 elements can't be seen so OSD info for channel change elements are hidden
 - The data rate of some channels is low (64kb) but
 RingBuffer::CalcReadAheadThresh doesn't handle these low rates which
 results in audio underruns.

 These patches
 1. Fix the channel changing & OSD issues.
 2. Fix the RingBuffer thresholds so that audio underruns are avoided.
