It was playable at a certain time even though there is no data on Timetable at that time. What was the problem ?

In case that a HDD has bad sectors and those sectors might corrupt time information in recorded data with a low possibility. This makes some recorded data invisible on Timetable.

To fix this, pelease execute “Reconsturct” feature in IDIS Solution Suite Setup.

The feature is to newly build time information table out of recorded data. The task of reconstructing time information is going to be running in the background.
