One thing to check is if the recording was interrupted, by going to the daily schedule which will tell you what show were interrupted and how. If there are no digital rights management locks that would prevent a complete recording, that would be the first and best way to begin troubleshooting the situation. other things that could affect recording would be power interruptions, or intermittent signal loss. the current software version and release dates in this series are: L7.22 for the model 722, issued 11Dec11, L7.50 released 11Nov, or L6.90 released 11Oct for the model 722k. If you are not on one of these versions, You will need to update to the most current version.
