After some searching around , the only information that i was able to 
collect was like this.

* DVB
packet length = 188/204/208
Sync word (First byte in packet) = 0x47

* DSS
packet length = 127/147
Sync word (First byte in packet) = 0x1d

Eventhough this is sufficient to transfer the data to userspace, but 
need more information to do something properly.
If somebody would like to see DSS and has some specs on DSS/DirecTV, can 
chip in some info.
