A channel is displayed online when the broadcaster’s profile logs in. There does not have to be a public stream at that time. Even if the channel is in a closed transmission, the channel is displayed as online but the stream cannot be queried.
Also the preview of the stream does not come from the stream directly but from images of the pages. XstreaMon tries to search for the stream in short intervals. So it can be that between going online of the channel and the start of the recording some time passes. The time interval is 30 seconds for automatic recording.
It also happens that the stream address is available but there is no stream data that can be retrieved. Then the recording starts briefly and is stopped again a little later.
