Usrp_tv_rcv.py and usrp2

Hi all,

Im a new user of the USRP2 (been playing with it recently)

I noticed that most of the code is written in gnuradio for usrp.
Im trying to use usrp_tv_rcv.py

Can someone point me to the right direction to what I need to know
when trying to port src from USRP to USRP2, also decimation changes
and sample multipliers .

Regards
