If vbi0 is already garbled then the problem is at the capture side. Can you
test with the capture test tool of the zvbi library? (See doc/README.vbi for
where to get it) That tool should show if the raw VBI is captured correctly
and determine if it isn't perhaps a bad reception.
I downloaded zvbi-0.2.16 but the zvbi.diff patch does not apply anymore.
However I tried without it and did not get any errors. Attached is the
output from
$ ./capture -vv -n --dump-cc
Is this test invalid without the patch?
Reception should not be the culprit as I do not get the garbled output
from vbi0/4 with 0.2.0rc3k.
