Options 

TS Input :
- Added DemuxPSI, DecodePAT and DecodePMT. Never tested which streams
  where PAT or PMT are splitted in more than one section.
- Some TS files still don't work (matrix.ts i.e : no sound ),
  others do ... i'll have to investigate.

Todo :
- What if data get unaligned ?
- Write NetworkOpen
- Try to find why I get no sound on matrix.ts
- Support Stream and program selection.
