 and goes - MORE DATA

Well I've been reading the mailing lists and found that when I have a
Mythtv Capture running and check out performance I get the following:

[root@...hbox bob]# v4l2-ctl -d 2 --log-status | grep 843
   cx18-0 843: Video signal:              present

If I was compiling from source there appears to be a way to force
fallback.  How this is done from the modprobe level on a package managed
system I have yet to figure out.
