short video clip showing distortion

Avermedia DVD EZMaker 7
Model: C039
VID:07CA PID:C039
Module used: cx231xx

When capturing analog video from my old Hi8 video camera (NTSC M), the captured video has banding and is grainy, it doesn't matter if I capture from the S-Video or Composite, the results are the same.

dmesg output:
