[DM800HD] Newbie Total Noob Queries

Hi Friends,

I have just installed Dreambox dm800hd. I am living in Belgium and one guy has set everything in the box so i receive all Indian and Sky Channels. I have a few questions.

1) Before i do anything i would like to take a total back up of the box so just in case if i try anything and something goes wrong i should be able to get these setting just the way it is right now.

2) When i press blue button - Graphical Multi Epg - Select a custom bouquet - i don't see any channels schedule. Only my current channel and current program and sometimes next program displayed. How can i view complete EPG?

3) How can i check what software am i using? I think i am using New Nigma 2. How do i check?

4) Is it possible to install new skins? If yes where can i find IPK files for my box?

5)I would like to stream videos (Avi,MKV etc) videos from my laptop to my TV(Samsung 46eh5000)(No smart, no internet). Is it possible to do this with dreambox dm800hd? If yes How?

I hope i receive some real good guidance.

Thanks in advance
