3 audio streams in 2 channels in Premiere

[Filippo]

Hello,
in adobe premier I put this video file which has 3 audio: Stereo Italian, 5.1 Italian Stero Japanese.
However, when I put it in Premiere, I see only 2 audio tracks, and if I solo each track, one is italian and the plays italian and japanese together at the same time. This happens even if I create a sequence by dragging the video on the new sequence button. I think it's a premiere error of interpretation because in MKVToolNix and ffmpeg the streams are 3, not 2. How can I fix this?

Thanks

Should be fixed now

Since I don't have Premier, I'm gonna take a guess that it either:
1- doesn't like the 6 Channels [possible channel mapping issue?], or
2- doesn't support ac3 @448 kb/s [possible bit rate limit?]

try:
1- reducing stream 1 to ac3, 6 ch, 192 kb/s first, and try it again in Premier
2- if that doesn't work, try re-mapping the 6-channels layout

you can do both in clever FFmpeg-GUI

Could be a muxing issue.
