RTSP memory buffer locking and ReadAhead logic modified.
setPacketReorderingThresholdTime() set to 0.5 (experiment)
Prefetching adjusted (might be too aggressive - needs testing). Some redundant code removed, and variable types adjusted.
More tweaks to pre-fetching
More experiments with RTSP client settings, plus buffer handling constants moved to TsReader.h
v73 test release (note: only compatible with MP 1.3.0 and later)

CheckPrefetchState() reverted back to normal behaviour for RTSP. RTSP maximum buffer size now 32MB, and an overflow situation now discards a chunk of the *tail* of the buffer.

Extra RTSP buffer logging added (when buffer logging is enabled).
Thread closing modified - demux thread is now closed in TsReader destructor.
MP1-4137 - modifies generation of tempPids so that it always happens when 'pidFound' is not true. Version info updated.
Add ATSC E-AC3 as stream_type, update copyright in modified files, and update version info.
Change log line formatting to get a better match with log4net logging.
Merge branch 'MP1-4137_TsReader_AC3_language_parsing_bug_v2' into MP1-EXP_TsReader_Area51_AC3_mods
Merge branch 'MP1-4171_TsReader_add_ATSC_E-AC3_stream_type' into MP1-EXP_TsReader_Area51_AC3_mods

Very minor log message 'banner' change
PacketSync changes (only).
Added changes that mm1352000 created.

Currently under testing with users in forum.
Based on 'BUG-3947-TSWriter-Deadlock-v2' branch, with async logging mods from 'EXP-TsWriter_async_logging', packetSync mods from 'MP1-EXP_TsReader_PacketSync', 'otherMux (0x46)' channel scanning mods from 'MP1-EXP_tvserver_0x46_scan_fixes' and minor Unicode logging fix manually merged into the code. Version resources also added.
Version info updated correctly....
Small logging changes to ensure log thread cannot be re-started after filter destructor is called.
"PCR_hunt_v3" patch applied (from http://forum.team-mediaportal.com/threads/dvb-c-radio-not-working.118141/page-5#post-986197 )
Previous logging mod mostly reverted (not an improvement...)
