Yes.  Most times mplayer and other video players will correctly stretch
the video to fill the screen, but I'm noticing on some broadcasts,
especially on Channel 12 playing an oldie but favorite, I will get a
black bar on the right when recording 720x480.  Recording 640x480 gets
rid of the borders when playing with mplayer, etc.

ctl_video_aspect/cur_val *is* set to 4x3 ... which is what I want.

Ah, it was just a thought. /me is a dummy with HD terminology.

Last time I watched HD (16:9) LCD TV, it made me sea sick. :-/
