Hi Andy, I am residing in the US and I am using the HVR-1600 to watch some broadcasting from my cable box (using s-video). A while back you had mentioned that you were going to work on the VBI issue of this card. I saw that you had completed support for sliced and raw VBI for 625 line system. I recently downloaded a fresh v4l-dvb copy from the mercurial deposit and compiled it. On my system (NTSC, s-video from a cable box), I still see the black and white horizontal line on the top. In one of your earlier email you wrote: "The wrong values for vblank and vactive may be being used in the cx18-av-core.c file."
Any idea what it would take to get this working for NTSC? I am more than happy to try out some changes.
