Choose restart in the live player
Open the live stream and select Play from Start when offered, or use the button at the bottom after choosing Watch Live. SBS says pressing it again can reach the previous programme while that start remains within the rewind window. This is movement within the live player; it does not establish a permanent recording of the complete channel.
Read the two-hour boundary literally
The help limits live playback to 120 minutes. When a programme began earlier, the player can offer Go Back 2 Hours rather than its actual beginning. A three-hour event therefore does not become wholly restartable merely because its title is still current. The current help also excludes Fetch and HbbTV from this feature, while documenting supported app, browser and casting routes.
Correct a small programme-boundary overlap
SBS bases restart points on EPG timings. If a programme ran over or under schedule, restart can briefly show the previous programme’s ending; the help directs scrubbing forward to the wanted beginning. That small overlap is different from reaching the two-hour limit. Use the timeline to correct the boundary rather than repeatedly restarting and returning to the same scheduled point.
Compare the right schedule for the stream
SBS’s live-guide help says internet channel streams follow the New South Wales schedule, while the online guide displays the time zone set on the device. A viewer elsewhere in Australia should distinguish that streamed appointment from the local free-to-air broadcast schedule. The guide also says only selected programmes later appear on demand; restarting a live stream is not evidence that the whole channel is archived.
