A bit too many options. This is sufficient:
ivtvctl -x 1 -w wss -b teletext,wss,vps
(-d, -u and -p are the defaults, cc is for NTSC, vps for TV-out is pointless
and so is raw).

I looked quickly at the code and it seems OK. You can check if it is recorded
OK by playing back a recording (cat rec.mpg >/dev/video16) and running the vbi
tool from the test directory (vbi /dev/vbi4). This reports the detected sliced
VBI
packets inside the mpeg stream. So you know that they are present.
I've also had reports that in certain circumstances the VBI capturing seems to
stop. I haven't had the chance to look at that.
