[vdr] VDR developer version 1.3.18 with NTPL

[Alfred Zastrow <vdr@zastrow4u.de>]

This change reintroduces the jumping problem between cuting marks when 
using NTPL.


------ schnipp --------

- Re-introduced a sleep to cDvbPlayer::Action() to avoid high CPU load 
in still
  picture mode (thanks to Reinhard Nissl for reporting this one).

------ schnapp --------


Who can afford the cpu load (about 0.50 during displaying a still 
picture and running one recording in the background on a duron 1300) and 
who want to use NTPL should comment out the else part in dvbplayer.c



                    }
                 }
//              else
//                 cCondWait::SleepMs(1); // this keeps the CPU load low
              }


best regards
Alfred
