Strange... did you check /var/log/messages?    'dmesg' accesses the 
kernel ring buffer, which only holds the last N lines logged by the 
kernel, so it's possible the ivtv-related messages have been lost.  
Check /var/log/messages instead.  Also, try rebooting, then checking 
for them, as you're guaranteed that the relevant messages won't have 
been archived away by logrotate.
