Mediaweek has a story on how the L3 local market measurements that measure program viewing for and includes three days worth of DVR viewing aren't catching on.  Not surprisingly, the problem seems to be that the local market ad buyers want to see measurement of commercial viewing plus 3 days at the local market level and don't want to rely on program viewing measurements.
