How should sps differ in the usrp source usrp and usrp sink?

At the beginning I had Sample rate = “760ksps = samp_rate*6” in UHD: USRP Sink & Source. PIC 1 (01_flowgraph)

But the file was not received and gnuradio gave me WHD: Warning.. PIC 2 (whd_warning)

1.Why are sps for source and sps for sink not the same?

2.When I wrote suggested sps to source and sink, I still could not receive the video file. Why?

3.1 But when I wrote sps = 704000 = samp_rate*5.5 to source and(!) sink, the video file was received! Why? PIC 3 (whd_warning_2)

3.2 But I still had WHD: Warning. Why?

4. How can I get the right sps I must use (exactly 711111 not 704000!)?

Thank you for your participation

Hi Pilot327, 

Since you're using gnuradio instead of LabVIEW with your USRP, I would recommend reaching out to support@ettus.com or posting on the ettus forums. More information found here: https://www.ettus.com/support

When you reach out or post again, I would recommend adding information on what specific hardware you're using also since from a glance at the screenshots, it looks like you have hardware related warnings.
