 I have an Pinnacle PCTV 310i (saa7134) and it was working fine, however,
 when I updated my kernel from the 3.17.1 version, the analog tv decoding
 stopped working correctly, the audio works but the picture is mostly green
 with some frames occasionally showing the actual video. The error occurs
 both for direct video playback and recordings regardless of the encoding I
 use (I tried with mpeg-4 and with the default rtjpeg).

 The only change I make is the kernel, if I start my machine with the
 3.17.1 version, it works fine, if I start the machine on a more recent
 version, (3.18, 3.19 or 4.0) the tv decoding stops working.

 The logs were made by starting the systems, opening the "watch tv",
 waiting a few moments for the tv decoding errors and closing the
 applications (using the 4.0.1 kernel version and "-v all" option). The
 v4l2 playback works well using mpv (with some strange log messages) but
 also fails with vlc ("rawvideo decoder warning: invalid frame size (622080
 < 933120)" ).
