[1]fix: quickinfo didn't work, if first cut-in point was greater than quickinfosize (on BytePos cut)
[2]fix: prevent to overwrite TS sourcefile on 'toTS', if output directory is the same as input
[3]change: 'toTS': simply align video/audio startcodes/synchwords in first pes-packet of each a/v-pid and for each split part (same as 'toMPG')

28.9.03 [3]change: 'toTS': simply align video/audio startcodes/synchwords in first pes-packet of each a/v-pid and for each split part (same as 'toMPG')
hatte sich wohl ein kleiner Fehler mit eingeschlichen...
jedenfalls fehlte mir da irgendwie das aligned'e AC3 syncword im ersten TS-pack davon?!

a bissl die Reihenfolge getauscht, nu sollt's passen..
