1) I am using "Channel properties" quite often because i need to switch between different audio streams (different languages of movie)
i think it could be nice if DVB dream has some little menu or switches for switching of audio. It could be helpful and faster than through channel properties. Same is about Radios, because they have more audio streams in one channel.
2) When DVB dream is switched to Radio station , it could be nice if instead "black screen" is there some audio visualisation wave, FFT for example. There could be informations about station too, and maybe switches of audio streams mentioned before

3) Many channels are using different format of screen. It could be nice if option Aspect ratio 4:3, 16:9,.. is included in setting of each channel and it will switch automatically when you switch channel. User will not need to adjust Aspect ratio always when he switch channel ..for example from News Channel 4:3 to Movie channel 16:9. Maybe it could be added to channel properties as it is probably not necessary to switch often.
