[mythtv-users] CPU power and decoding

[Milos Prudek]

I would like to build a MythTV box (frontend/backend in one PC). Are the 
following sentences true or false?

- DVB broadcasts in MPEG-2; consequently there is no encoding taking 
place when saving a DVB broadcast to disc.

- When watching a DVB broadcast, the CPU must decode MPEG-2, or the DVB 
card's onboard hardware MPEG-2 decoding takes place.

- When watching an analog TV broadcast, no significant decoding takes 
place and the burden on the CPU is very light.

- When recording an analog TV broadcast, the encoding done in software 
via CPU will consume less than 1GHz of processing power.

- When watching a DVB broadcast, the decoding done in software via CPU 
will consume less than 1GHz of processing power.

- When buying both a DVB card (the new SkyStar1 CI) and an analog 
terrestrial TV card, I will need only one remote control (for example 
the SkyStar's remote control), and I will be able to control the whole 
MythTV with it, i.e. both the DVB and analog card.

- It is actually possible to have a wireless IR keyboard, wireless IR 
mouse and IR remote control, all working, not disrupting each other 
(equipment recommendations/buying advice welcome).

Thank you very much for any input on these presumptions.

I'm in Europe.
