Hey, everyone.

I have imported 2 videos to my Pinnacle Studio 21 Ultimate, which originally contain Surround 5.1 audio, 448kbits, 48KHz.
I have joined the 2 videos into a single video on my timeline but when I try to export it, the application shows only 2 audio channel options; mono and stereo. I have even tried checking the "same as timeline" box but it still shows those 2 audio channel options. Therefore, the video can only be exported in stereo with 192 maximum bitrate as the best possible option.
Pinnacle Studio 21 supposedly supports 5.1 surround audio export. Does anyone know how I can "unlock" it and export videos with 5.1 audio 48KHz?

Thank you.
