I have seen this before (I don't have redring installed). The box did not crash and reboot, but it became unresponsive to the remote and locked up part way through a timer recording. The buttons on the front panel also stopped working, but I could still get Telnet access. I rebooted after the scheduled end of the recording (Telnet) and the recording was there but seemed too short. The programme played back in full but the progress bar halted part way through. The recording (TS file) was complete but the HDR-FOX stopped writing to the sidecar file (NTS) part way through. You can fix the recording. If you bookmark the start and end of the programme and crop, the sidecars are fixed in the process.Funny that watching the same recording it seems it does not progress beyond 1:06. The progress bar stays there but the video still played for the last half hour. Might be related?
