This firmware adds the ability to scan EPG of other channels using the second tuner, when not recording and not standing by. EPG of all channels should show up in roughly 15 minutes for the current broadcast channels.
These models are no longer supported. No new feature can be added. Users are highly recommended to trade them in for current models. If you experience any serious problem with this firmware, please downgrade to the official firmware on Magic TV web page.
0. Magic TV subtitle setting is per-channel and per-recorded-programme. There is no global setting.
1. When you record a program, the current subtitle for that channel is stored as the default subtitle for the recorded program. Therefore, you must make sure every TV channel has chosen a subtitle - when playing live TV, change to each channel, and select a subtitle. (You only need to do this once after autoscan. Since you're asking this question, it means you did not do this.)
2. If you switch subtitle during playback, it is stored as well for that recorded programme only. There is no reason this setting should be lost, unless you cut power without standing by first.
