Note when the box joined the channel
The manual describes automatically saving up to two hours of the channel currently being watched. If Record is pressed partway through that viewing, it can record from the point the channel was tuned. The key boundary is therefore not merely when the programme began in the guide. It is also when the receiver began holding that channel’s material.
Use a concrete viewing example
If a film started at eight but you switched to that channel at half past eight, do not assume pressing Record later can reconstruct the opening half hour. By contrast, if the box was already tuned to the film from its beginning, the saved material may cover that earlier part within the documented limit. Check the resulting recording rather than promising a complete film from the guide title alone.
Distinguish rewind from an available restart service
The same manual limits live rewind to two hours or the point of tuning, whichever is earlier. A broadcaster’s online Watch from Start facility, where offered, is a separate route and depends on its own availability. Rewind history on the receiver does not establish that every programme can be restarted from the beginning through the internet.
Choose the right action for future viewing
For something important, schedule a recording in advance and verify the planned item rather than relying on a late decision during the programme. If a recording lacks its opening, look for a legitimate repeat or complete replay and check its accessibility presentation. Describe the tuning time and recording action to support; those details explain much more than the statement that the Record button lost part of a film.
Questions, answered
Can Record recover footage from before the receiver tuned to the channel?
The manual only describes saved material from the point of tuning, within its limit.
Are temporary rewind and an online Watch from Start service identical?
No. They are separate routes with different conditions.
