Terrible image capture

  • Hi !


    First of all thanks for taking the time to read my question, I really appreciate it.


    Here it is, it's my first try and I bought all the necessary materials.


    I'm having trouble with image reception, it's supposed to look like this :



    The image i get is like this :



    I'm receiving TV from my internet box, it goes into a HDMI 2 RCA, then to a USB Grabber plugged in my raspberry pi 3 (B+).


    I've used this guide (french) : http://opendomotech.com/faire-…ht-raspberry-et-hyperion/


    Can you give me some directions ?


    The RCA cables were quite expensive, however the USB grabber and HDMI 2 RCA both came from aliexpress (not the cheapest one of the website either), but I wouldn't bet on it being top quality.


    Thank you in advance

    Do you have a PAL NTSC switch? Try to change the format with that...best would be if you can test the signal after the hdmi2rca with a tv...
