[Discuss-gnuradio] ./usrp_rx_cfile capture and ./benchmark_rx capture di

Subject: [Discuss-gnuradio] ./usrp_rx_cfile capture and ./benchmark_rx capture differs in bit-rate set even with same parameters

Dear list,
  I have a question. I just want to make sure I am not hallucinating infront of my comp here. I run this script as follows:
1. ./usrp_rx_cfile.py -f 2.4G -d 128 foo.dat @ the receiver
=> I get, the bitrate set to 500k

But, when I run this script as follows:
2. //benchmark_rx.py -f 2.4G -d 128 @ the receiver
=> I get the bitrate set to 250k.
Even though, both has decimate rate set to the same, 128.

Problem is, I am running "./benchmark_tx.py -f 2.4G -i 256 --from-file=foo.txt" on the receiver side, and it sets my bitrate to 250k as expected. I would like to get the same bitrate at the receiver side when running "usrp_rx_cfile capture [see 1]", with (interpolation/decimate) still being equal to 2. Because I want 2 samples per symbol. Can somebody tell me if there is anything obvious about this that i am doing wrong or a parameter configuration that I can pass which will do what i need. Let me know if I need to give more details of the purpose. Thank you very much.
