Pip and streaming


I have two question about progdvb and twice satelite tunner.

1) if I want see on two diferent channel from different satelite(HotBird,Astra 23.5) why screen frozen about 5 seconds?

2)it is possible streaming channels in pip mode?
Because I can’t choose channel in streaming settings.I see only primary channel and few random channels.this list of channel always change if I change channel.

It is not userfriendly :-)
