Ok after 2-3 hours of playing around, got it working:

$ cat video.sh

#!/bin/bash

# Set video type.
echo s-video > /sys/class/pvrusb2/*/ctl_input/cur_val
echo NTSC-M > /sys/class/pvrusb2/*/ctl_video_standard/cur_val

# The only option I need:
echo "65535" > /sys/class/pvrusb2/sn-*/ctl_volume/cur_val

# The following was found here:
# http://www.mail-archive.com/pvrusb2@isely.net/msg00306.html
#echo "10485760" > /sys/class/pvrusb2/sn-*/ctl_video_bitrate_peak/cur_val
#echo "8388608" > /sys/class/pvrusb2/sn-*/ctl_video_bitrate/cur_val
#echo "Constant Bitrate" > /sys/class/pvrusb2/sn-*/ctl_video_bitrate_mode/cur_val
#echo "224 kbps" > /sys/class/pvrusb2/sn-*/ctl_audio_bitrate/cur_val
# modify, sound is too low (max is 65535)
#echo "65535" > /sys/class/pvrusb2/sn-*/ctl_volume/cur_val
#echo "53738" > /sys/class/pvrusb2/sn-*/ctl_volume/cur_val

# Now you can mplayer /dev/video0!
# mplayer -vf yadif /dev/video0

Mplayer works flawlessly.

Note using USB, there is a delay ~2-3 seconds vs. the TV itself.
