Clarfications on Reliance HD DVR

Hi,

I live in Bangalore and planning to buy Reliance HD DVR option for my home.

I decided this based on south channels and my interest in watching/recording the documentaries in
Discovery and NGC

If someone has already purchased/using this service let me help in following points

1. Pros/Cons in this service.
2. There is no dicovery HD channel listed in reliance site. Do we get discovery HD now?
3. If we record the programme can we copy it to local desktop/computer. If yes what is the file format?

Any other info if I missed.

Thanks
Guhan
