Inserted PSI Packets No Longer Cause PowerKEY

CAQAM Reboots
In earlier releases, when the DNCS was in ATSC mode with Open Cable Compliance
selected, the PowerKEY CAQAM would occasionally reboot. These reboots did not
occur when the DNCS was in DVB-SI mode or when Open Cable Compliance was
not selected. When Open Cable Compliance is selected, PSI packets are inserted into
the CAQAM. This condition could also occur in other configurations (for example, if
the SI Insert Rate is set lower than recommended). CR 54738 corrects this issue.
