Titanium PCIe SB0880, analog 7.1 and upmix films 5.1- 7.1

Question

I have:
- Creative X-Fi Titanium PCIe sb0880 (purchase march 2009),
- Drivers and software from Daniel_K last 3.0a version (08.25.2014),
- Acoustic system 7.1 with ampliefer (without audio processor, there no hardware mixing of MultiCH stereo and so on as reciever),
- Analog connection between the amplifier and soundcard (3.5" miniJack).
In theory, which works in Windows XP (or worked before, I used it until 2010) for my soundcard, upmix from 5.1 ac3-track to 7.1 (5.1 -> 7.1 with adding 2 sides virtual channels from mixing by X-Fi built-in decoder) must be as follows:
In my Windows 8.1 driver's Decoder tab is missing. I tried to install a different versions of the driver (Official and Daniel Kawakami) with complete cleaning system (with registry entries and ultimate uninstall) but in vain — desired options don't appear. I have found these support posts:
- No Decoder Option on Sound Card
- Suggested Setup to Perform Decoding with your Playstation 3
Then similar posts on this forum:
- Decoder tab missing with latest X-Fi driver
- X-Fi: Decoder tab missing?
There staits that now decoder option is not available in Titanium driver — use the Cyberlink PowerDVD soft. It really works (with software Cyberlink audio decoder in PowerDVD):
But how to use the Cyberlink decoder for other players? Or maybe there are other ways to get the same result with Dolby Pro Logic IIx software decoder or with enabling built-in Decoder tab in my driver?

Thank you for your clever response. I've been using this set.
In Media Player Classic (K-Lite Codecs Pack) when playing a movie from a multichannel track there is activated ffdshow audio decoder (mixer 3/2/2 - 7 channels + LFE):
When playing a 5.1-tracks don't work 2 side speakers (Side ch.), the decoder shows the following information:
When playing a 7.1-track works all speakers, and the decoder shows, all working good:
Perhaps the only required setting Media Player Classic and ffdshow audio decoder, to achieve this. While I solved the problem by copying the sound signal from rear channels (Surround/Back) to the side speakers (Side ch.) by mixer in ffdshow. But this is only a temporary solution (russian language interface):
PS: Creative's CMSS3D and DTS Neo:PC just makes upmix 2.0->5.1/7.1 (very impressive!) but never 5.1->7.1...
