Subject: add possibility to set per service ac3/pcm delay (not yet via gui) to
 set a pcm or ac3 delay for a specific service edit your servicelist
 (/etc/enigma2/lamedb) example for pcm delay:

6dca:00c00000:044d:0001:1:0
Das Erste
p:ARD,c:000065,c:010066,c:020068,c:030065,c:060001,c:080060 <-- 0x60 = 96ms PCM delay

for AC3 delay set, c:07xxxx
