More info, new test.
>From my S-VHS player, when there is no tape inside, there is a blue
image with program number in white. This is a still image, stable
without any static.
I captured this image and got errors and drops at very regular time.
Looking at the output log, I took the time for 15 errors. All of them
are separated by 16-17 seconds.
Between the errors there are warning messages
Past duration 0.xxxxx too large
where 0.xxxxx increase at a regular time.
