Hi agavin, okay, I have an update on this issue: I don't think it's a bug in the current git version, actually I think it does the correct thing.
I tried around a lot and noticed that with some videos, it was behaving correctly. So I investigated what the difference was. Apparently when I used an old version of ffmpeg to do the AVHCD -> MKV wrapping, it attached to the video the metainformation that it was encoded with 1000 fps when in reality it were merely 25 fps. I've checked and all videos that I rewrapped in the past have the 1k fps setting. The old kdenlive version however ignored that nonsensical fps setting. The new kdenlive/melt version pays attention to it (at least when "speed" is active) and this seems to create the undesired sideeffect that I described. What I did was rewrap the MKVs again and specified the "-r 25" setting, copying video and audio data to fix the framerate. After this change, it all worked perfectly. Sorry for the fuzz but maybe it's good for reference in case anyone else runs into that same issue.
