The "Event Result" table
is a result of enabling "Save Time Stamps" on the IPTV tab of the IPTV device block. So if you aren't seeing it, try enabling "Save Time Stamps" and rerunning your test.
NOTE: Be careful If you are running a long IPTV test as enabling this option since it will take cause the resutls file to grow quite large. For example a 30 minute test with a zap interval of 4000 msecs for 160 emulated STBs resulted in a 19.5 MB results file.
