Avermedia DVD EZMaker 7 Model: C039 VID:07CA PID:C039 Module used: cx231xx Distro: Manjaro Kernel version: 6.13.0-1 Components used: Conexant CX23012-11Z (according to https://www.linuxtv.org/wiki/index.php/AVerMedia_DVD_EZMaker_7_(C039)) 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. On my windows PC the capture is perfect. dmesg output: [31173.105709] cx231xx 3-1:1.1: New device AVerMedia TECHNOLOGIES, Inc.
