Video storage relies on index files (.idx) that map timecodes to physical data segments. If the recording device shuts down abruptly (power loss, improper shutdown) or the hard drive develops bad sectors, the index can become corrupt.

This cause is especially suspect if the error occurs for a specific time window or channel, while other channels play back fine.
