Recordings Reported as Failed "Unable to Track"
In the event that a recording has missed its start point (possibly by only a few seconds), it will be reported as broken on playback "unable to track". It will still play though. If there is no recording (other than a failed marker), the programme start marker did not occur while the Humax was watching for it (from 15 minutes prior to the nominal EPG time to 30 minutes or more after).
There are other broken recording reports, eg loss of signal or loss of power, but always attempt to play the recording because frequently these are only glitches at the start and it is (to all intents and purposes) in fact intact.
