Dolby Surround, Dolby Prologic or Prologic 2 on SD TV (1 Viewer)

[doornjoostje]

I read on the website of my cable supplier that normal SD digital tv can be broadcasted in Dolby Surround, Dolby Prologic or Prologic 2.

Dolby Surround, Dolby Prologic and Prologic 2 is 2 channel stereo upmixed to 4.0 or 5.1
How see: Dolby Pro Logic - Wikipedia, the free encyclopedia

I watch my HTPC to watch SD digital tv in 99% of all cases.
How to setup my HTPC in such a way, that I get surround sound?
Does anyone have an example Dolby Surround, Dolby Prologic and Prologic 2 MPEG 2 recording, that I can download, in order to be able to check if my system is properly set.

My details (More, see my system specs):
GigaByte GA-MA78GM-S2H v1.0 with onboard Realtek ALC889A.
Analogue 5.1 boxes, directly plugged into the realtek.

Any help would be greatly appreciated and if I tell anything that's not true, please tell me.
in advance!

No audiophiles out there?

Found it out myself.
In the settings od the Realtek ALC889A i've enabled DTS connect.
Futhermore also set the output as 48k with 24 bits sound.
Now enable Prologic 2 sound in PowerDVD settings ans there it is.
